General Description

• The run concerns the observation of the galaxy group IC1370 with VIMOS
   and is composed of
  1 OB in imaging mode with 2 broad band filters (B and R) and 4 OBs for IFU spectroscopy
   centered on two different positions on the galaxy group, with grisms HR_blue and
   HR_orange, sampling 0.67 arcsec/fibre and
  FoV 27''x27''. No dithering was planned, since objects occupy a big fraction of
   the FoV and therefore it is not possible to program a useful dithering pattern without
   loosing a significant fraction of the target.
  Among IFU observations, priority should be given to the pointing on a, b, f galaxies
   (IFU_IC1370abf_HR*). For a given pointing, the OB with the HR_blue grism (IFU_IC1370xxx_HRblue1)
   should have priority over that with HR_orange grism (IFU_IC1370xxx_HRoran1).
  As an additional calibration with respect to those already present in the VIMOS
   Calibration Plan, we added the IFU observations of 2 radial velocity/Lick standard
   stars with the HR_blue grism. Their execution is planned only once during the run
   and they are intended to be used with any of the IFU+HR_blue observations of IC1370
   that will be completed.

Waiver Requests

• The Waiver Request 076.B-0764A.01 for overriding the 1 hour time limit
   of individual OBs for VIMOS-IFU observations, submitted on 2005-07-22 has been approved
   by Paranal Science Operations on 2005-07-26.

Critical Observing Condition Constraints

• We ask that imaging (OB IMG_IC1370) be executed with airmass < 1.5
   and seeing better than 1.0 arcsec.
  We have relaxed our initial constraints for IFU observations (OBs IFU_IC1370xxx)
   and ask they are executed with airmass < 2.0 and seeing better than 1.3 arcsec.
  Moon angular distance is required to be > 60 deg for all IFU target observations
   and > 90 deg for the imaging (IMG_IC1370).

Time-Critical Aspects

• The only constraints on time arise from the observability of the target
   and calibration stars.
  
  The target IC1370 culminates at 1:17 UT and reaches airmass 1.5 (2.0) at about 4:00
   UT (4:55 UT) on Oct 1st. It is observable for sufficient time at the beginning of
   the night until Nov 10th, 1:20 UT, for observations with airmass < 1.5 (i.e.
   imaging); until Nov. 10th, 2:15 UT for long observations with airmass < 2.0 (i.e.
   IFU + HR_blue grism); until Nov. 18th, 01:45 UT for IFU observations with HR_orange
   grism and airmass < 2.0.
  All UT times given above are intended as time of end of exposure.
  
  Calibration stars are observable from the beginning of the observing semester until
   the following dates:
  HD211038: latest possible observing date 2005 Dec 10th, UT 01:50 (time of end of
   exposure).
  HR203: latest possible observing date 2006 Jan 10th, UT 02:10 (time of end of exposure).

Special Execution Requirements

• Taking into account the achievement of minimal science goals,
  preference should be given to the execution of IMG_IC1370, IFU_IC1370abf_blue1,
   IFU_IC1370abf_oran1, before proceeding to the execution of IFU_IC1370bcd_blue1 and
   IC1370_oran1.
  For both IFU_IC1370abf and IFU_IC1370bcd the execution of the OB with the blue grism
   has priority on the OB with the orange grism.

Special Calibration Information

• The observation of 2 radial velocity and Lick/IDS standard stars with
   VIMOS_IFU is requested once during this run for calibration of IFU observations
   of IC1370. They are necessary for studying the kinematics and the population indices
   of the target galaxies. These observations are not required to be contiguous to
   any particular science observation. They are intended to be excuted in the case
   that at least one of the IFU science OBs with grism HR_blue is executed.
  The 2 stars are: 
  -- HD211038  Spectral Type K0/1V  B=7.44 mag   V=6.54 mag
  -- HR203     Spectral Type G2V    B=6.76 mag   V=6.15 mag
