RA Range: 3.5 (single field)

Constraint set (Typical seeing, Transparency,Airmass, FLI, Moon distance):
1.0 PHO 1.2 0.0/0.4 180

  Long program, simple broadband imaging of a deep field divided into 
several areas.

  Program needs the standard photometric calibrations in BVR.
No special calibrations needed, and no time constraints.
 
Period 70:
Observation of a spectrophotometric standard star in U#877, U#841,
I#845, I#879. Magnitude of spectrophotometric standard SA95-42:
V=15.61, A type star.

The spectrophotometric standard star SA95-42 is observed in the old
and new U and I filters. Standard calibration for U/50 and I#879.

Non-standard calibration U and I twilight (FS-F* OBs) and dome flats
(FD-F*-1, FD-F*-2, FD-F*-3 OBs) to be observed before and after the
corresponding OBs for the spectrophotometric standard are carried
out. Three different sets dome flat OBs for different exposure levels
are provided. One of each should be carried out during each
calibration.
