General Description
** These observations are designed to help detect high proper motion stars
in the core of the globular cluster
Omega Centauri (NGC 5139). As such they simply consist of two sequences of repeated
jitters in the H band. The first sequence is of short DITs, designed to cover the
brightest stars in the field, and the second sequence is of longer DITs, designed
to reach as faint a limit as possible and maximize the stellar sample. The only
constraint on the observations is that each star needs to be able to be centroided
as accurately as possible -- hence our requirement for good seeing (better than
0.8"). There are no calibration OBs. The offset throw to sky fields is large (1000"),
to get away from the crowded central cluster regions and out towards the cluster
tidal limit.
** The brightest object in this field will be a star in the SE corner of the field,
which is a magnitude or so below the top of the RGB, with V ~ 12.5. This corresponds
approximately to H ~ 8 at brightest.
** Four finding charts have been provided. One complies with the required NACO constraints
(ie 2x2' field, etc). The remainder have smaller fields of view, and are designed
to allow fine centering of the observations. Reference stars are always marked,
as is the field of the selected S13 camera, the target name, orientation, and scale.

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 ?
If you have PSF reference star OBs, do the names of those OBs begin with
PSF_ ?
If there are Finding Charts attached to your OBs, is the field-of-view
of at least one of these charts 2' x 2' (with clearly labelled field orientation)
?
Have you clearly marked and labelled your wavefront reference objects
R1, R2, R3, ... (as specified in the NAOS Preparation Software) on your Finding
Charts ?
Have you specified the magnitude of the brightest object in the field-of-view
for each OB ?
Are there objects in any of your fields (including standard stars) which
are brighter than the limits specified in the User Manual and on NACO web Pages
?
If the previous answer is yes, have you given a list of OBs and a justification
for the brightness limit violation in the general description field ?
