Notes. Columns 1 and 2 provide the identifier for the star following the nomenclature of Fi99a and Li09 respectively. Columns 3 and 4 provide co-ordinates. Column 5 provides the most up-to-date spectral classification available from either Fi99a or Li09, while Col. 6 provides our revision. Finally Col. 7 provides any additional widely used identifiers (e.g. WR number and the naming convention of Dong et al. 2011). qF309 and −344 are re-classified via comparison of the spectra from Fi99a and Mauerhan et al. (2010a) to our new data. The five Quintuplet proper members are those stars with MGM 5-# identifiers (Moneti et al. 1992). QX# and QR# indicate radio and X-ray detections reported in Lang et al. (2005) and Wang et al. (2006) respectively. The Pistol star is also reported as a radio source but no new identifier is assigned for it, while the X-ray designation of qF344 derives from Muno et al. (2009). Tuthill et al. (2006) provide the orbital period for qF211 and suggest periods in the hundreds of days for qF243, −251, and −258 based on the size of their dusty nebulae.
