General Description

• The main goal of our XMM-Newton Distant Cluster Project (XDCP) is the
   identification of very distant (z>1) X-ray luminous clusters of galaxies.
  This identification program consists of one 16min R_special-band and one 8min z_Gunn-band
   images which is sufficient to detect an overdensity of red galaxies out to z~1.5.
  It is essential for the scientific goals to obtain accurate z- and R-band photometry.
   Calibration for the R_SPECIAL filter can be obtained as part of the standard calibration
   program, whereas extra z_Gunn standard star observations (one per night) are needed
   (see section 'Special Calibration Information').

Special Calibration Information

• Every night that one or more science OBs are executed in Photometric conditions
   (each OB is a differen target), one photometric standard should be observed in Z_Gunn
   from the list of 7 Sloan standards (Smith et al. 2002) provided (OBs called CAL*).
   Please pick a standard with RA as close as possible to the target(s) observed in
   that night. 
  
  The exposure time of 1 sec for these standards stars (all fainter than 11.5 in R)
   should be adequate to get >~10000 ADU, but please double check the peak value
   to make sure is not saturated.
  
  If the z-standard star OBs (prefix 'CAL') with appropriate RA have already been
   executed at a different night, the z-standard calibration observations should be
   performed during twighlight ('free of charge'), using the OBs with prefix 'TWI'.
   Again, please observe at least one 'twighlight z-standard' for every night science
   targets are observed.
