Major Instrument Modes: FORS2 MXU

RA Range: 10h

Constraint set (Typical seeing, Transparency,Airmass, FLI, Moon distance): 0.8 2CLR 1.6 0.1 90.


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


Special Remarks:


 
 
MXU spectroscopy of a blank region of the sky to look for emission line
galaxies. Unusual setup: GRIS_300I and z_special are used *simultaneously*.

The acquisition strategy is rather peculiar, but well documented in the
README file: manual offsets, specified in the README file for each of the
science OBs, are required once acquisition is complete. If more than
one OB is excuted sequentially, the acquisition template should be
executet with PRESET=F.

A 10 second image without filter is taken after every spectroscopic exposure.

The feasibility of this strategy was demonstrated by 66.A-5657(A).

A waiver was granted on 14 August 2001 to allow the user to manually
edit the FIMS files.

Since calobuild cannot handle the GRIS_300I-z_special combination, the
user has submitted one daytime calibration OB (114946). The exposure
times are set to the minumum value and should be changed to the
correct one before executing it.
