These data compose the largest available sample of SMC clusters with spectroscopically derived abundances and velocities. Our clusters span a wide range of ages and provide good areal coverage of the galaxy. Description: V- and I-band pre-images of our target fields were taken by ESO Paranal staff in 2005 August as part of Program 076.B-0533. The spectra of the program stars were obtained during 2005 November in service mode by the VLT staff, using the FORS2 spectrograph in mask exchange unit (MXU) mode. File Summary:
