General Description

This is a plain imaging program.
We will observe the same field (named BDF4, Bremer Deep Field 4) in the Y filter
 for a grandtotal of 17 hours (including overheads).
I have selected a standard dithered procedure. 
Each OB is about 1hr long, for a total of 17 OBs. 
Only the first one is required to be photometric, for calibration purposes.
OBs have PA orientation of 0, 90, 180 and 270 deg to allow for a proper masking
 of electronic defects and cross-calibration of the mosaic images.

Critical Observing Condition Constraints

Apart from the general constraints on seeing and moon illumination,we
 have set no special criteria for observations

Time-Critical Aspects

In principle, this program does not have any time-critical aspect. However,
 our recent analysis of the Hawk-I Science Verification data has shown that high
 redshift SN may be confused with the z=7 galaxies that we are targetting. In the
 SV data, we have been able to remove SN in the Y band data based on the analysis
 of the images taken in two different epochs, with a time lag of 1month. For this
  reason, we would be grateful if the Y band data can be taken in two different epochs,
 with at least one month of separation.
