Data for deriving the color-magnitude diagram

To derive the color-magnitude diagram we need $V$ and $I$ exposures. With two months of $B$ exposures we should have enough for a deep CMD.

Observations needed:

3 x (10,10)sec in $V, I$ (Rotator position = 0 ) 3 x (10,10)sec in $V, I$ (Rotator position = 180 ) 3 x (120,90)sec in $V, I$ (Rotator position = 0 ) 3 x (120,90)sec in $V, I$ (Rotator position = 180 ) 3 x (360,240)sec in $V, I$ (Rotator position = 0 ) 3 x (360,240)sec in $V, I$ (Rotator position = 180 )

The notation means (1. line): 3x10sek ($V$) + 3x10sec ($I$).

If these observations can be aquired fairly early during the run I (Frank) can reduce them to construct CMDs such that we can evaluate the data and see whether we need further shifted and rotated images to compensate for flat fielding problems. The CTIO and Siding Spring telescopes do not need to do these observations
