Spectral type for the components of the AB pair (2007ApJ...660.1480M). ASAS-3 magnitudes contaminated by Pismis 24 16 (V= 13.02; O7.5V; sep. 12"), Pismis 24 18 (V= 13.97; B0.5V; sep. 15"), Pismis 24 17 (V= 11.84, O3.5III(f*); sep. 16"), Pismis 24 19 (V= 14.43; B1V; sep. 16") and Pismis 24 12 (V= 13.88; B1V; sep. 21"). Range has been corrected and corresponds to the combined brightness of the AB pair. |
