| The table below gives standard magnitudes measured through B, V, and I filters for the standard stars used to calibrate our images of M5. 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 | 126 | 14.112 | 12.787 | 11.497 |
| B | 547 | 14.210 | 12.994 | 11.700 |
| C | 659 | 14.261 | 13.082 | 11.838 |
| D | 1174 | 14.172 | 12.887 | 11.469 |
| E | 1034 | 14.014 | 12.887 | 11.674 |
The two Cepheid IIs in M5 are V42 and V84. Watch this space for color-magnitude diagrams!
Below are the uncalibrated V light curves for V42 (Period=25.7 d) and V84 (Period=26.9 d), respectively. The photometry derive from images taken at the Macalester Observatory.
