General Description
A deep imaging program of 2 fields containing a high redshift (z~5) QSO,
in order to find galaxy clusters around them. Deep imaging is to be performed in
the R, I and z bands to enable high redshift candidates selection using the 'dropout'
technique by applying an appropriate colour cut.
The two targets have been choosen to have coordinates that span the semester. The
targets are at RA of 03hrs and 12hr, and given the difference in RA, the service
observer does not have to wait for a night when both targts are available!
We have defined the indivdual z-band exposures to be 120secs, longer than that recomended.
We do this because this observation plan has been very succesful in the past and
maximises the available observational time within the 1hour OB.
We ask that care is taken when observing the z-band photometric standard field.
Generally, the central star in the z-band standard fields is the only one in the
field with published Z band photometry, consequently it must not be saturated.
We have had other programmes in the past where the service observation saturated
it because the observer reasonably, but erroneously, expected the other stars in
the field to be calibrated. This is not true of most Z-band fields in our experience.

Pre-imaging Requirements
Source(s) of Pre-imaging
Pre-imaging sources not listed above
Do all your OBs comply with the instrument-specific requirements listed
on the instrument-specific Phase 2 web page ?
If this is a pre-imaging run, did you select PRE-IMAGING for the Observing
Category for each Observing Template ?
Do all your finding charts comply with both the general and instrument-specific
Phase 2 Web Pages ?
If you submitted OBs for standard stars, did you specify the magnitude
and spectral type of all standard stars in the OBs ?
Have you included OBs for any calibrations that you need but which are
not part of the Calibration Plan ?
If you are observing Moving Targets, have you attached suitable ephemeris
files to your OBs?
If you have preferences which OBs should be executed first, did you make
use of the User Priority field in the OBs ?
If this is a run that requires coordinated observations with other facilities,
did you give proper instructions in the Time-Critical Aspects Section ?
If you have prepared your finding charts with tools other than FIMS,
do they comply with the specifications on the FORS1 Phase 2 web page ?
