Notes. The objects used for the distance estimate of NGC 3603 are set in boldface style. We rejected the other objects based on their RUWE factor or discrepant proper motions. The supergiants NGC 3603 23 and NGC 3603 25 (i. e. Sher 25) were rejected because their ages are incompatible with the cluster isochrone of 1 to 2 Myr (Melena et al. 2008). Star identifications for the first 16 objects are from Sher (1965), for the following five objects from Melena et al. (2008) and for the final two objects from Baier et al. (1985). (a)From Table 3 of Melena et al. (2008) except for NGC 3603 56, for which the spectral type of the primary component from their Table 1 is given. (b)Photogeometric distances (Bailer-Jones et al. 2021).
