General Description
This program (82.D-0339) serves for the preparation of the Gaia astrometric
satellite mission. Gaia will not only measure precise astrometry of 10e+9 stars,
but also radial velocities, abundances, logg and Teff of a large subset of the target
stars. The purpose of this program (and all others related to observing the Ecliptic
poles) is to achieve a database for initial checks of functionality and performance
of the satellite once in space. Here we will obtain data to evaluate Gaia's hi-res
spectrograph. We are thus observing stars with magnitudes between 14.5 and 16.8,
near Gaia's spectrographic sensitivity limit.
Some remarks about this p2pp package:
-------------------------------------
-Magnitudes are only good to about 0.3 mag (our imaging data on which positions
and magnitudes rely was not photometric), the position have been derived against
UCAC2, they should be better than those of UCAC2, currently about 0.1"
-The main goal is to get high S/N data for as many stars as possible. Therefore
three of the four OBs (per grism) for each pointing should have been observed, before
moving to another field. While there are not really priorities for the different
pointing, it would be prudent to start with the central field.
-The finding charts have been prepared with skycat, they are normally oriented (i.e.
East to the left, and North up, the orientation is also marked) and 25'x25' in size
as required. The differnet fibres are represented by the blue and red symbols, the
GS is marked by the red diamond, the fidicual stars be the red squares. The field
centre is marked by a red point witihn a blue circle without any star inside.

Do all your OBs comply with the instrument-specific requirements listed
on the instrument-specific Phase 2 web page ?
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 ?
Did you specify in your OBs the hour angle range for which your Target
Setup files are valid ?
Did you specify in your OBs the magnitudes of FACBs and Guide Star for
all your fields ?
Are the FACBs and Guide Star in the brightness ranges specified in the
FLAMES manual ?
Did you enter the expected signal to noise in your OBs ?
