General Description

This programme is the continuation of a project 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 14 groups. The WFI photometric data will be used
 to identify fossil groups potentially present in the sample and to construct the
 photometric luminosity function for the galaxies of each group. Our science goals
 require photometric conditions. Exposure times longer than 15 minutes will
provide S/N larger than 10 for galaxies with R=23.5.

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 OPC priority class
 assigned
to this 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

Out of the present sample of 14 groups, 9 are observable under suitable
 conditions
throughout the whole period 76. The remaining 5 targets are observable under suitable
conditions from Nov 2005 or Jan 2006 on.
