The table below gives standard magnitudes measured through B, V, and I filters for the standard stars used to calibrate our images of M12. Each star is indicated by both a letter which corresponds to the markers in the above picture and its Stetson identification number. Currently, there are not local standard stars for this cluster.

ID	Stetson ID	B Magnitude	V Magnitude	I Magnitude
A	N/A	N/A	N/A	N/A
B	N/A	N/A	N/A	N/A
C	N/A	N/A	N/A	N/A
D	N/A	N/A	N/A	N/A
E	N/A	N/A	N/A	N/A
