Estimated Total Execution Time (hours, including overheads)

General Description

• We want to obtain IFU spectra over a large range of radii within a single
   galaxy. To achieve the necessary S/N we have to keep the IFUs for a long time integrating
   at the same position. The IFUs closer to the center can be repositioned since they
   will gather signal faster. Thus, the first 2 science OBs have the IFUs in the same
   position, the last 3 science OBs also have a common position for the IFUs. Only
   two IFUs change position within the whole program. The remaining OBs are dedicated
   solely to obtain spectra from 6 radial velocity standard stars. Note that we have
   to turn the SimLamp OFF in order not to contaminate our science spectra with strong
   Argon lines. We do need, however, wavelength calibration. Thus, we require, following
   the information in the web pages, 60 sec integrations with the SimLamp ON before
   and after each science exposure, bracketing the long science exposure with the lamp
   OFF. This procedure has been granted by a waiver and it is already implemented in
   all OBs.
  
  On the Finding Charts: blue crosses mark the positions of the sky IFUs; a red diamond
   marks the VLT Guide Star; red squares mark the FACB stars; blue circles mark the
   positions of the IFUs on science targets and standard stars; and finally a thick
   blue circle marks the field center.

Waiver Requests

• A Waiver Request to have Observing Blocks with 2 hours was submitted 10
   days before the Phase 2 deadline (on July 24) and approved by Francesca Primas on
   July 27. This waiver makes these observations more efficient as it reduces significantly
   acquisition overheads.
  
  A Waiver Request to perform wavelength calibrations with 60 sec exposures with SimLamp
   ON bracketing the main science exposure with SimLamp OFF, instead of simultaneous
   calibration, was submitted on August 8 and approved by Francesca Primas on August
   10. This procedure is implemented in all OBs, including those referring to our target
   galaxy and the standard stars. It is necessary to avoid contamination of the science
   spectra by the lamp lines.

Critical Observing Condition Constraints

• These are as in every OB.

Time-Critical Aspects

• OB1 to OB5 and OB9 will start to be hard to execute from February
  
  OB6 can not be done from December
  
  OB7 and OB8 can not be done from January

Special Calibration Information

• We need spectra of a few radial velocity standard stars to be able to
   obtain the velocity distribution in our target galaxy. We thus carefully selected
   6 stars, spanning a range in spectral type and these observations correspond to
   OB6 to OB11. There are no special needs for the observations of these stars. They
   span a range in right ascension so during the full period a few of them can be observed.
   Note, however, that some of them can only be observed during a couple of months
   of so. These are their V magnitudes and spectral types (note that these are bright
   stars!):
  
  OB6:  HD 203638  -  5.41  -  K0III
  OB7:  HD 223311  -  6.07  -  K4III
  OB8:  HD   8779  -  6.41  -  K0IV
  OB9:  HD  22484  -  4.28  -  F9IV-V
  OB10: HD  66141  -  4.39  -  K2IIIb Fe-0.5
  OB11: HD  83516  -  8.63  -  G8IV
  
  On wavelength calibration for standard stars: since these are bright and need short
   exposures, it might be that we can take simultaneous wavelength calibration with
   the SimLamp ON, but PLEASE CHECK that the spectra of the standard stars are not
   contaminated by the Argon lamp lines. If this is the case, then we request 60 sec
   integrations with the SimLamp ON before and after each OB, bracketing the standard
   star exposure with the lamp OFF, as for the first OBs.
