• 12:35:00

General Description

• This project is aimed at searching and characterizing "fossil" groups
   in the whole Southern
  Emisphere. Suitable candidates are selected from the REFLEX survey. In this programme,
  we require WFI imaging (down to R = 24) for a complete sample of 22 groups. The
   WFI photometric
  data are necessary to select the 2 targets that will be followed-up within this
   semester
  in medium resolution spectroscopy (down to R = 21.5) with VIMOS+MOS (075.A-0716(B,C)).
  Thus, our main science goal is time critical and requires photometric conditions.
   As for
  the WFI imaging, 15-minutes exposure times will provide S/N about 10 for galaxies
  with R = 23.5.

Waiver Requests

• No Waiver Request was submitted for 075.A-0716(A). Conversely, Waiver
   Requests
  for runs 075.A-0716(B) and (C) were filed on Feb 15 2005 and granted (on Feb 16
   2005)
  until the necessary WFI data have been analyzed by us.

Critical Observing Condition Constraints

• Our main science goal needs accurate photometry. Hence the sky transparency
   has to be
  photometric and the image quality has not to be poor. Given the time-critical aspect
  of our project, we have partially released the constraints for airmass, lunar illumination
  fraction, and Moon angular distance. This strategy has no critical effects on the
   depth and completeness of this survey however.

Time-Critical Aspects

• As anticipated in Sect. 13 of our proposal and in the General Description
   of this programme,
  runs 075.A-0716(B) and (C) may be planned and executed only once the WFI data are
   fully
  acquired, reduced, and analysed. Hence, as a special requirement, this WFI run should
   start
  being executed in April and finished as late as May 20.
