Estimated Total Execution Time (hours, including overheads)
General Description
The program is straightforward J band imaging of point sources selected
on their (very)
red i'-z' colour in wide-field CCD images from CFHT. The IR imaging is needed to
distinguish
between brown dwarfs (which have red z'-J colour) and quasars at redshift=6 (which
have
neutral/blue z'-J colour; their very red i'-z' is due to the redshifted Lyman break
and
their spectrum is otherwise mostly flat).
The coordinates are good to better than an arcsecond, and given the pointing accuracy
of the NTT and the SOFI field of view finding charts are unnecessary.

Critical Observing Condition Constraints
Conditions need to be photometric to within ~5% (i.e. very thin cirrus
is tolerable, but
really not much of it).
Since we are dealing with isolated point source, additional integration time can
(within reason) be traded against seeing.

Is this a Pre-imaging run ?
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 ?
