Major Instrument Modes: FORS1 IMG_HR

RA Range:1hr

Constraint set (Typical seeing, Transparency,Airmass, FLI, Moon distance): 0.6 1PHO 1.5 0.1 90


Pre-imaging run? No! Chilean run? No! Special calibrations? No!
Time critical? No! ToO? No! Carry-over run? No!


Special Remarks:


   
 
Waiver approved for combining 2 filters in same OB.
Waiver approved for long exposures.

Time constraint: PI requests the OB's need to be executed in order
through the full sequence. There are two sequences in total but these
two sequences do not need to be observed on the same night.

I have mailed the user to explain that good seeing will be hard to
maintain for the long duration of their sequences especially given the
time pressure in the early part of the period when their target is
visible. They have now decided that OK they cannot expect <0.6
throughout and will be happy with a median seeing of 0.8 (but left the
OB's with the approved 0.6" constraint). The waiver form the mountain
explains to them that although they will start the sequence when the
seeing constraint of 0.6" is met they will continue to execute the OB
no matter what then happens and this is understood by the PI.
