General Description

• This is a straightforward long-slit spectroscopy program to measure the
   major axis velocity dispersions and rotations of a sample of early-type galaxies
   in the Fornax cluster.  We also include observations of several radial velocity
   standards.  The FORS2 Calibration Plan data are adequate for our needs.

Waiver Requests

• No Waiver Request was submitted

Critical Observing Condition Constraints

• Please note that the slit should be rotated to align with the major axis
   of each galaxy, as indicated in the OBs.
  
  We require dark time (moon illumination < 0.4) becuase the surface brightnesses
   of these galaxies are fainter than the sky at 3 days from new moon, and hence if
   spectra were obtained during brighter skies the exposure times would have to be
   increased substantially.
  
  We need seeing of 0.8 arcsec or better because of our chosen slit size of 0.5 arcsec,
   which is required to achieve sufficient spectra resolution to resolve the velocity
   dispersions of the galaxies in our sample.
  
  Photometric conditions are not necessary, however we request that the observations
   not be done in cloud cover more than thin cirrus.

Time-Critical Aspects

• There are no time-critical aspects of this programme.

Special Execution Requirements

• No special execution requirements.

Special Calibration Information

• No special calibration is required, we can use the standard FORS Calibration
   Plan data.  However, we have included OBs to observe several radial velocity standard
   stars.
