Abstract:
    This catalog is the result of combining the spectral types in
    2011ApJS..193...24S (Paper I) and 2014ApJS..211...10S (Paper II), the
    first two major papers of the Galactic O-Star Spectroscopic Survey
    (GOSSS). Together they constitute Data Release 1.1 of the survey and
    they supersede the previous 1.0 release from June 2013. Most of the
    spectral types for northern ({delta}>-20{deg}) stars are from Paper I
    and all of the spectral types for southern ({delta}<-20{deg}) stars
    are from Paper II. However, for some northern stars the spectral type
    is from Paper II.

Note (1): exists only for the stars studied in paperII (ref=S14). The symbols
     include "SB1" (single-line), "SB2" (double-line), "SB3" (triple-line);
     the question mark (?) indicate possible spectroscopic binaries; and
     the "E" stands for "eclipsing".
