The table below gives standard magnitudes measured through B, V, and I filters for the standard stars used to calibrate our images of M10. Each star is indicated by both a letter which corresponds to the markers in the above picture and its Stetson identification number.

ID Stetson ID B Magnitude V Magnitude I Magnitude
A 58 N/A 13.558 12.073
B 8 N/A 14.262 13.441
C 62 N/A 12.600 11.009
D 23 N/A 13.900 12.659
E 40 N/A 13.197 11.719
F 18 N/A 14.029 12.668
