Major Instrument Modes: FORS2 MXU

RA Range:13hrs

Constraint set (Typical seeing, Transparency,Airmass, FLI, Moon distance): 1.0" 2CLR 1.7 0.4 90

Time critical? No! ToO? No! Carry-over run? No!


Special Remarks:


 
 
This is MXU spectroscopy using pre-imaging of the galaxy cluster A1689
taken on April 1st with FORS2. Note that only 1 mask is being observed
here, and all the OB's are just repeat exposures of the same field, so
the overhead should be small.

The targets are very faint high-z candidates and will not be visible in
through slit image unless they have emission lines (in the red).

Reference stars should be visible in the through slit
exposure, and not all are likely to be stars, some may be 
compact galaxies.
