The dataset lists all the confirmed globular clusters (GC), all the known candidates GCs, and also all the objects that were identified as candidate GCs in the past and were subsequently recognised not to be genuine clusters, each entry being properly classified (GC, candidate GC, foreground star, background galaxy, HII region, etc.). The latter entries are maintained in the catalogue to avoid re-discoveries of objects that may look like M31 GCs and have been already classified as non-GCs. Please take into account the classification flag(s) when you use the RBC. Request for Acknowledgement: Please acknowledge the use of this catalogue.
