General Description

• This programme is to observe a number of stellar fields in the Galactic
   Bulge region with  VIMOS/IFU for radial velocity spectroscopy. Each pointing is
   observed for 1 hr with VIMOS/IFU, HR-blue grisms. 2 exposures are taken at each
   position. The pointings are clustered in 6 fields (corresponding to HST images).
  
  Good seeing (0.8") is required to extract he individual star spectra from the cubes.
   Grey sky is acceptable as the bulge itself provides quite some background light
   anyway.
  
  One pointing is included that was observed before, for consistency - this one, as
   well as one pointing per field, have highest priority. Otherwise it is preferred
   to complete each field to a similar degree (i.e. better 2 to 3 pointings per field
   than one field with 10 pointings). 
  
  Each pointing has a particular PA associated with it - this is to ensure the IFU
   lines up with the HST images. If there are operational reasons to relax this requirement
   this is possible (after consultation).
  
  Radial velocities accurate to 0.5 pixels=0.25A=15km/s are required. Thus the on-sky
   calibrations are crucial.

Special Calibration Information

• I have included 6 OBs for a radial velocity standard star - if possible
   each one should be observed on the same night as the bulge fields. 
  The star is very bright (V=5.2) and could be observed in twilight (perhaps instead
   of the spectrophotometric standard in the Cal Plan?). 
  
  There are also 6 OBs for observing a dark patch in the bulge, in order to obtain
   a sky spectrum. These should be observed as close to the time of the bulge observation
   as possible, ideally interspersed between them. They do not need any kind of seeing
   quality, but will be useless if the sky conditions have changed a lot.

If you submitted OBs for standard stars, did you specify the magnitude
 and spectral type of all standard stars in the OBs ?

• YES

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?

• N/A

If you have preferences which OBs should be executed first, did you make
 use of the User Priority field in the OBs ?

 did you give proper instructions in the Time-Critical Aspects Section ?

• N/A

Did you specify suitable guide stars for all your OBs using Guidecam
 ?

• N/A

Did you check that the chosen guide stars are suitable for all the offset
 positions and that they do not produce unacceptable vignetting of the field of view
 ?
