Major Instrument Modes: ISAAC SWI, Al-L, Hw-J, H, Ks, NB 2.09, NB 2.1

RA Range: 06:12 (single cluster)

Constraint set (Typical seeing, Transparency,Airmass, FLI, Moon distance):
0.6 3THN 1.4 1.0 30.

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

Special Remarks:
Contains a bright star, which slightly (factor 2) saturates in J,H,K. Do not execute the SW-BB under substantially better seeing than specified! 

 


Broad- and NB imaging of an embedded young star cluster.
One of the SW-OBs (S255-IR SW 2) contains 3 different NB filters.
The brightest star(s) in the FOV saturate slightly in the SW broad
bands (they were granted a WR to do this, and finish their sequence
with a sky field), therefore do not execute that OB (S255-IR SW 1) under 
seeing conditions better than specified (slitghtly worse is acceptable)! 
The other OBs are fine wrt saturation.
