Adopted cluster centre: star 57. Hyades | Lynga's selected angular diameter was taken. References (2) and Hyades | (240) cite star 56 as a blue straggler. Star 56=68 Tau=HD 27962 Hyades | has a spectrum A3V and an optical companion of magnitude 9 (45). Hyades | The blue straggler does not show anomalous lithium abundances Hyades | (39). In (2) this star is given a spectrum Am(K/H/M=A2/A3:/A5) Hyades | and a projected velocity v.sin i=18km/s. IC 166 |The colour-magnitude diagram shows an important dispersion in the IC 166 | turnoff area. Star 459 could not be identified on the chart. IC 348 |The cluster is given an age of 5-20 Myr in (316). IC 1311 |The photometric study (6) surveys an area that seems to be IC 1311 | displaced from the cluster centre. Stars 22, 281 and 361 are IC 1311 | cited as blue stragglers in (6) and the presence of several IC 1311 | `red stragglers' candidates is also pointed out. IC 1369 |Adopted cluster centre: star 57 (140). All blue stragglers lie on IC 1369 | the periphery of the cluster but they are members according to IC 1369 | (140). In particular, notice the close group of IC 1369 | stars 155-156-157. IC 1442 |Star 49(G=11.56, G-R=0.65, U-G=1.06). Adopted cluster centre: IC 1442 | star 82 (380).

IC 2488 |Reddening and age are from (262). Adopted cluster centre: IC 2488 | star 28 (262). Star 37(B8) is cited as a likely blue straggler IC 2488 | in the same reference. IC 2581 |The de-reddened colour-magnitude diagram was examined (328). IC 2581 | Stars LSS 1529 and LSS 1563 have spectra O7V and B0.5II IC 2581 | respectively (43). IC 2602 |Theta Car=HD 93030 is a well-known blue straggler. In (163) this IC 2602 | star is given the magnitudes v=2.78, b-y=-0.094, m1=0.063, IC 2602 | c1=-0.078, beta=2.603, spectrum: B0Vp. Reference (240) gives it IC 2602 | a projected velocity v.sin i=195km/s. Theta Car is a IC 2602 | spectroscopic binary of period 1.77 days and eccentricity 0.446 IC 2602 | (363), thought to be the result of a mass transfer event in a IC 2602 | close binary an account of this interpretation may be found in IC 2602 | (96). IC 2714 |Star 157 is considered to be a cluster member in (67). IC 2714 | Identification chart was not available. IC 2944 |Star designations are HD 101... . Star 131(O7n) is a IC 2944 | spectroscopic binary. Star 190 has a spectrum O6 (320). IC 4651 |The colour-magnitude diagrams in (9) and (88) were examined. IC 4651 | Identification chart is in (221). The CCD photometry (9) IC 4651 | considers stars 9, 10, 18, 46 and 94 as probable binaries and IC 4651 | also suggests the presence of many binaries in the turnoff area. IC 4651 | Stars 9, 40, 46 and 75 are cited as blue stragglers in (88). IC 4651 | Stars 9 and 75 are non-members and star 46 (A5IV) is a probable IC 4651 | cluster member according to (221). The DDO photometry of cluster IC 4651 | giants (306) has found CN overabundance on them. Attention is IC 4651 | drawn to the possible relation between this fact and the blue IC 4651 | straggler phenomenon (306). Other clusters with blue stragglers IC 4651 | and CN-strong giants: Mel 66, NGC 2204, NGC 2420, NGC 2682, IC 4651 | NGC 7789 (306).

The ubvy-beta photometry (297) gives: IC 4756 | 104(v=9.24, b-y=0.170, m1=0.051, c1=0.839, beta=2.804). IC 4756 | Star 104 is cited as a probable blue straggler in (297). Adopted IC 4756 | cluster centre: star 236 (159). IC 4996 |Proper motion study (350) was consulted. The ubvy-beta photometry IC 4996 | (7) gives 5=HD 228706(v=8.75, b-y=0.108, m1=0.178, c1=1.195, IC 4996 | beta=7.878). Adopted cluster centre: star 2 (165). IC 5146 |The cluster is given an age of 3 Myr in (372). IC 5146 | Star 42=BD+46 3474 has a heavily reddened B1V spectrum (367). King 2 |Reddening and age are from (380). The colour-magnitude diagram is King 2 | probably contaminated with field stars, so only candidates King 2 | inside r/R=1 were considered. Adopted cluster centre: King 2 | star 419 (374). King 8 |Star 105(F3V) belongs to the field according to (52). King 11 |Reddening and age are from (12). Adopted cluster centre: King 11 | star 315 (12). King 12 |In (256) the cluster is given an age that is intermediate between King 12 | those of NGC 884 and NGC 2362 groups. Lynga 1 |Reddening and age are from (271). Markarian 18 |The de-reddened colour-magnitude diagram was examined (260). Markarian 50 |11=BD+59 2682. Adopted cluster centre: star 33 (136). Melotte 20 |= Alpha Persei cluster. Star 835(B3.5) is a cluster member Melotte 20 | according to the proper motion study (157). Stars 835 and Melotte 20 | HD 22928(B6n) are cluster members according to their radial Melotte 20 | velocities (273). No identification chart was available. Melotte 66 |In (207) it is suggested that a spread in the metal abundances Melotte 66 | may account for the observed dispersion around the turnoff in Melotte 66 | the cluster colour-magnitude diagram. In that case, several Melotte 66 | stars that appear as blue stragglers would not be such. Melotte 71 |Reference (276) gives the cluster E(B-V)=0.10 and age=0.93 Gyr. Melotte 105 |The photometric study (200) gives the cluster E(B-V)=0.52 and Melotte 105 | age=0.15 Gyr. Adopted cluster centre: star 57 (304). Melotte 111 |= Coma cluster. Chart and star identifications in (326). Adopted Melotte 111 | cluster centre: star 91 (326). Star 146=17 Com=HD 108662=AI Com Melotte 111 | is a cluster member (326) and an alpha CVn variable (240). It is Melotte 111 | cited as a blue straggler in (2), (170) and (240). Reference (2) Melotte 111 | gives this star a projected velocity v.sin i=15km/s and a Melotte 111 | spectrum A0Vp(Sr, Cr, Si, Eu). NGC 129 |Magnitudes are from two photometric studies: (15) and (165). NGC 129 | Proper motion study: (212). Adopted cluster centre: NGC 129 | star 100 (15). NGC 188 |Stars on areas I and II in the identification charts of (287), NGC 188 | with a membership probability p>=80% (344) were taken. Reference NGC 188 | (342) gives the cluster E(B-V)=0.12. The CCD photometry (187) NGC 188 | discovered a probable FK Com variable (star V8) which can be NGC 188 | considered as a `red straggler' candidate. An hypothetical NGC 188 | relation between the blue stragglers and the apparent lack of NGC 188 | bright giants in the cluster nucleus is discussed in (187). In NGC 188 | the photometric study (98) the following stars are cited as blue NGC 188 | stragglers 1003, 1005, 1032, 1033, 1043, 1093, 1102, 1103, 1112 NGC 188 | and 2046. In (342) and (344) it is suggested that the cluster is NGC 188 | somewhat younger than what is usually agreed, so several stars NGC 188 | that appear as blue stragglers would not be such. NGC 381 |Reddening and age are from (71). Adopted cluster centre: NGC 381 | star 79 (71). NGC 433 |Reddening and age are from (22).

Stars 32 and 85 NGC 559 | are probable non-members according to their colours and spectra NGC 559 | (141). NGC 581 |Proper motion study: (260). NGC 637 |Reference (171) gives this cluster E(B-V)=0.66, (B-V)o=-0.27 NGC 637 | (turnoff) and age=15Myr. NGC 654 |Colour-magnitude diagrams in (269) and (314) were examined. The NGC 654 | proper motion study (314) gives to star 3: spectrum B3, p=90%. NGC 654 | Adopted cluster centre: star 44 (269). NGC 659 |Colour-magnitude diagram in (141) was examined. Adopted cluster NGC 659 | centre star 119 (279). NGC 663 |Adopted cluster centre: star 21 (347). NGC 752 |Identification chart and proper motion study (82). Another NGC 752 | membership study: (275) gives star 209=BD+36 367 a probability NGC 752 | p=99%. The ubvy photometry (341) gives: 209 (v=9.74, b-y=0.028, NGC 752 | m1=0.153, c1=1.002). Reference (96) cites star 209 as a blue NGC 752 | straggler and star 110 as a `red straggler'. References (161) NGC 752 | and (170) also cite star 209(B9.5p?) as a blue straggler.

NGC 2099 |Star 6 is cited as a blue straggler in (240). NGC 2112 |Reddening and age are from (284). The colour-magnitude diagram is NGC 2112 | probably contaminated with field stars. NGC 2158 |The colour-magnitude diagram shows an ill-defined turnoff. The NGC 2158 | photometric study (53) gives the cluster E(B-V)=0.55 and NGC 2158 | age=3 Gyr. In Table 2, `d' stands for `double' according to NGC 2158 | (14). The apparent cluster diameter was taken from (141), NGC 2158 | although the distribution of the blue stragglers suggests a NGC 2158 | larger size.

References (2) and NGC 2632 |(240) cite star 265=HD 73666=40 Cnc as a blue straggler. NGC 2632 |Reference (2) gives star 265 a spectrum A1Vp(Si) and a projected NGC 2632 |velocity v.sin i=40km/s. NGC 2660 |The colour-magnitude diagram shows an important dispersion (146). NGC 2660 | The reddening seems to be variable across the cluster area. NGC 2669 |2=HD 75105(B8III/IV), 24=HD 75067(B8/9IV/V(n)), spectra are from NGC 2669 | (169). Adopted cluster centre: star 8 (360). NGC 2682 |= M67. This cluster has a number of well-known blue stragglers. A NGC 2682 | detailed spectral analysis of these stars may be seen in (231). NGC 2682 | The extended photometric study (292) was used. It includes all NGC 2682 | those stars with a membership probability p>50% according to the NGC 2682 | proper motion study (291). The identification chart may be found NGC 2682 | there. Adopted cluster centre: star 1023 (291). All the NGC 2682 | candidates with p>=80% were listed. The following are the NGC 2682 | membership probabilities and the often-quoted Fagerholm (99) NGC 2682 | designations of some of the blue stragglers: 145(94%), 277(93%), NGC 2682 | 740(87%), 751(96%), 752(95%), 821(89%), 856(90%), 968=F153(95%), NGC 2682 | 975(90%), 977=F81(93%), 984=F134(95%), 997=F124(93%), NGC 2682 | 1005=F95(95%), 1031(91%), 1036(91%), 1066=F156(90%), NGC 2682 | 1072=F136(95%), 1082=F131(99%), 1165(93%), 1183(95%), 1195(96%), NGC 2682 | 1263(89%), 1267 (93%), 1273(91%), 1280(93%), 1284=F190 (95%), NGC 2682 | 1434(91%), 1440(94%), 1947(86%), 2204=F130(83%). The UBV NGC 2682 | photometry (281) includes another star (not listed in the NGC 2682 | catalogue) 1242b(V=12.73, B-V=0.37:, U-B=0.09, r/R=0.38). A NGC 2682 | possible relation between the blue stragglers and the `clump' NGC 2682 | stars is discussed in (90). In (272) the five bluest blue NGC 2682 | stragglers are studied and two of them (F190 and F280) are found NGC 2682 | to show infrared excesses that are interpreted as signs of the NGC 2682 | presence of evolved companions (i.e. they may be Algol-type NGC 2682 | binaries). In the case of F190, the binary character has NGC 2682 | received support from the discovering of radial velocity NGC 2682 | variations. These have been interpreted (242) as manifestations NGC 2682 | of a binary with a period 4.18 days and eccentricity 0.205. This NGC 2682 | star and theta Car in IC 2602 seem to be, at present, the best NGC 2682 | candidates in support of the mass transfer theory to explain the NGC 2682 | blue stragglers. However, the blue straggler F81 is above the NGC 2682 | magnitude limit that the same theory predicts, although its NGC 2682 | membership is still under discussion (231). Besides, F190 and NGC 2682 | F184 are small-amplitude pulsating variables of delta Sct type NGC 2682 | (130). In (230) it is shown that the spatial distribution of the NGC 2682 | blue stragglers (strong central concentration) is similar to NGC 2682 | that of the cluster binaries; an evolutionary relation between NGC 2682 | the two populations is suggested (230). Star 1082 would be an NGC 2682 | X-ray source (28). (97) cites several `red stragglers', and NGC 2682 | (230) considers star F136 as belonging to an evolutionary stage NGC 2682 | related to the blue stragglers (it is a binary star). Through NGC 2682 | the determination of lithium abundances on some blue stragglers, NGC 2682 | a form of mixing affecting their external layers has been NGC 2682 | proposed (90). NGC 2818 |Colour-magnitud diagrams in (264) and (324) were examined, the NGC 2818 | last one covering a more extensive area. Star 108 is not NGC 2818 | included in (264). NGC 2910 |Identification chart and tables of magnitudes were not available. NGC 3033 |Adopted cluster centre: star 11 (360). Both stars would be NGC 3033 | non-members according to the same reference. NGC 3105 |Star 101 has a spectrum Be(H-alpha emission) (118). It is NGC 3105 | considered a cluster member according to its reddening and NGC 3105 | distance modulus. NGC 3114 |Adopted cluster centre:star 141 (225). The colour-magnitude NGC 3114 | diagram is probably contaminated with field stars. The apparent NGC 3114 | cluster diameter was taken from (301). In the ubvy-beta NGC 3114 | photometry (298) stars 8, 9, 14, 15, 16, 18, 61 and 124 are NGC 3114 | considered as blue stragglers candidates according to their NGC 3114 | position in the beta-c diagram; five of these stars show NGC 3114 | peculiarities. From the same reference are the following NGC 3114 | spectra 3(B8III), 8(B8.5IIIp/B9p(Si)), 9(B2IVp/B3V), NGC 3114 | 10 (B8III/IV). NGC 3293 |The colour-magnitude diagram in (339) was examined.

Stars 228 and 243 are cited as blue stragglers in NGC 6791 | (129). Stars SE09 and 223 are probable field stars according to NGC 6791 | (197) and (129) respectively. Reference (197) also draws NGC 6791 | attention to the presence of several `red stragglers' which are NGC 6791 | probable cluster members. The CCD photometry (188) mentions the NGC 6791 | existence of a possible FK Com variable star; no contact NGC 6791 | binaries have been found. NGC 6802 |The colour-magnitude diagram in (165) shows an important NGC 6802 | dispersion; only candidates inside r/R=2 were taken. Adopted NGC 6802 | cluster centre: star 82 (165).

Star 897 could not be identified on the chart. NGC 6819 | Stars with p>50% (288) and inside r/R=3 were taken, although not NGC 6819 | all the candidates are included in the proper motion study. NGC 6819 | Star 552(p=49%) was also included. Stars 16*, 22*, 37, 133, 285, NGC 6819 | 419, 522, 687, and 889, are cited as blue stragglers in (16). NGC 6834 |Colour-magnitude diagrams in (128), (165) and (245) were NGC 6834 | examined. Reference (170) cites star 5' as a blue straggler, but NGC 6834 | in (332) it is considered to be a normal evolved star that NGC 6834 | appears bluer because of the differential reddening. NGC 6871 |4=HD 227634(B0Ib), 5=HD 190864(O6), 7=BD+35 3956(B0.5V, RV var.), NGC 6871 | 8=HD 227586 (BII-III), 9=HD 227611(B0pe), spectra are from (69).

Stars 70 and 77 NGC 6940 | (numbers of (352)) are cited as blue stragglers in (129) and NGC 6940 | both are probable cluster members. NGC 7031 |Adopted cluster centre: star 30 (151). NGC 7039 |According to (300) there would be two clusters: the first one at NGC 7039 | 700 pc, and the second at 1500 pc having two blue stragglers. NGC 7039 | Adopted cluster centre: star 182 (150). NGC 7062 |Adopted cluster centre: star 50 (165). Proper motion study: NGC 7062 | (184). 31(p=43%), 37(p=31%). NGC 7082 |Adopted cluster centre (star 19) and apparent cluster diameter NGC 7082 | are from (150). NGC 7086 |Adopted cluster centre: star e (148). NGC 7142 |Adopted cluster centre: star 130 (72). NGC 7235 |Adopted cluster centre: star 5 (165). Star 4 has a spectrum NGC 7235 | B1V (245). NGC 7243 |Identification chart in (27). Adopted cluster centre: star 1. NGC 7243 | Reference (162) gives star 370 the magnitudes v=9.95, b-y=0.052, NGC 7243 | m1=0.093, c1=0.528, beta=2.742 and a spectrum A0Vp. It is a NGC 7243 | cluster member according to its radial velocity and proper NGC 7243 | motion (p=96%) (211). NGC 7245 |Adopted cluster centre: star 102 (376). It is a non-member NGC 7245 | according to (376), where star 8 is given the magnitudes NGC 7245 | G=12.87, G-R=0.78, U-G=1.75. NGC 7380 |Membership study: (17). NGC 7788 |Adopted cluster centre: star 8 (26). NGC 7789 |The first selection was based on the photometric study (38), NGC 7789 | which is complete (it includes stars up to 7.5' from the cluster NGC 7789 | centre) though rather old. There is no identification chart in NGC 7789 | (38). Star designations and coordinates may be found in (206). NGC 7789 | The second selection took into account the detailed membership NGC 7789 | analysis for each blue straggler (35). Consequently, stars NGC 7789 | considered in (35) as non-members are not included in the NGC 7789 | catalogue. Reference (35) also gives the following categories: NGC 7789 | non-member? to stars 168, 192, 1047 and 1119; member? to stars NGC 7789 | 197, 409 and 934; member to stars 88, 282, 316, 342, 371, 453, NGC 7789 | 677, 696, 746, 1095, 1168, 1211 and 1270. Star 677 seems to be NGC 7789 | above the magnitude limit that the mass transfer theory NGC 7789 | predicts, and star 1211 is on that limit (36). An extensive halo NGC 7789 | of blue stragglers was described in (235), but these stars would NGC 7789 | belong to the field (343); at most, the stragglers have the same NGC 7789 | radial distribution that the cluster giants (343). In the ubvy NGC 7789 | photometry of 28 blue stragglers (343) there appears to have no NGC 7789 | peculiar stars among them, except star 1211 (Ap); in general, NGC 7789 | the objects seem to have evolved from the ZAMS. Reference (318) NGC 7789 | gives this cluster E(B-V)=0.31 and age=1.6 Gyr. NGC 7790 |The UBV photometry (265) gives the cluster E(B-V)=0.64. Stars A NGC 7790 | and B are probable members according to (265). Star A is cited NGC 7790 | as a blue straggler in (240).

The authors assign the Roslund 3 | cause of the unusual positions to high rotation velocities. Ruprecht 36 |Star 1=CD-26 5011 is a non-member according to (359). Adopted Ruprecht 36 | cluster centre: star 5. Ruprecht 44 |Star LS 909 has a spectrum O8:e (312) and is a probable member, Ruprecht 44 | although it may belong to the Pup OB2 association of which this Ruprecht 44 | cluster seems to be the nucleus (249).
