General Description

• This program aims to investigate the properties of AGN host galaxies by
   making IFU observations of X-ray selected AGN at low redshift that already have
   HST imaging data.
  
  There are 4 science targets (reduced from the original 6 in the proposal due to
   the extra overheads incurred by having OBs shorter than the total time needed for
   each target), targetted with multiple OBs, as the total exposure time is greater
   than 1 hour (note that an waiver has allowed longer OBs but this is not sufficient
   to complete observations in any given object - the waiver allows 2x40 mins on target
   per science OB).   In order to calibrate the spatial PSF, which we need to do to
   subtract of the AGN component, we have a set of PSF calibration stars in separate
   OBs that must be observed directly after the science OBs (also allowed via a waiver).
    The calibration PSF stars were choosen to be bright stars V~10-11, of type G8III-K2III
   near to the science targets.  The stellar type of these stars allows them to also
   be used a radial velocity templates.
  
  The connecting between PSF star and science targets is as follows:
  science target     PSF star          Number of science OBs    Number of PSF OBs
  MS1138.1+0400   CSI+06-11429              2                         2
  MS1158.6-0323   HD106174                  2                         2
  MS1408.1+2617   CSI+19-14114              3                         3
  MS2144.9-2012   HD208446                  2                         2
  
  A second critical aspect is that flexure within VIMOS over the typical 40min exposure
   time we are using is not so great that the spectra of adjacent fibres are significantly
   blurred, as this will make extraction of the data hard, if not impossible.  There
   is no problem with having shifts due to flexure between frames, it is only a problem
   during a single frame.
  
  Note that the OBs for MS1158.6-0323 contain an offset sky exposure (offset by 30"
   in RA) between the two object exposures (which are at the same location).  This
   is due to the source almost completely filling the IFU field of view.  The offset
   sky is shorter than the on target observations, as the target is bright and not
   sky limited.

Waiver Requests

• Waiver requested on 13th Jan 2006 
  Granted 16th Jan 2006
  
  Waiver: 077.B-0519A.01.WAV [APPROVED]
  
  Waiver granted for individual science OBs to be longer than 1 hour (2x40 mins exposure
   time plus overheads).
  Waiver granted to link observations of OBs together to a maxiumum of 2 science OBs
   + 2 Calibration OBs.
  
  This is in order to reduce the impact of readout noise on the science observations
   and obtain PSF calibrations that are taken at the same time as the science calibrations.

Critical Observing Condition Constraints

• After each science OB there must be a PSF calibration OB observed.  There
   is a separate PSF calibration OB defined for each science OB.  They relate to each
   other as follows:
  science OB             PSF cal OB
  IFU_MS1138.1+0400_1  IFU_CSI+06-11429_CAL_1
  IFU_MS1138.1+0400_2  IFU_CSI+06-11429_CAL_2
  IFU_MS1158.6-0323_1  IFU_HD106174_CAL_1
  IFU_MS1158.6-0323_2  IFU_HD106174_CAL_2
  IFU_MS1408.1+2617_1  IFU_CSI+19-14114_CAL_1
  IFU_MS1408.1+2617_2  IFU_CSI+19-14114_CAL_2
  IFU_MS1408.1+2617_3  IFU_CSI+19-14114_CAL_3
  IFU_MS2144.9-2012_1  IFU_HD208446_CAL_1
  IFU_MS2144.9-2012_2  IFU_HD208446_CAL_2
  
  A waiver has been granted to enable a science OB followed by a PSF calibration OB
   to be taken.  Infact the waiver allows for the combination of 4 OBs as follows:
   science+cal+science+cal, this is prefered but not required for our observations.
    Our minimum requirement is 2 Obs together: science+cal.

Special Execution Requirements

• ---(Empty)---

Special Calibration Information

• We take PSF calibration star observations directly after each science
   OB.  These also double as velocity templates.  The first observation of each such
   PSF star is placed in all 4 quadrants, subsequent observations are only placed in
   one quadrant.
