General Description

We propose to spectroscopically verify distant X-ray luminous clusters
 of galaxies. 
At this point, we submit the first 3 masks for which the preimaging data is available.

The currently submitted masks are for the candidates:
XMMU J023605.1-522510.0
XMMU J225635.5-363156.8
XMMU J000322.6-300355.8

Two more masks have now been added:
XMMU J235616-344141
XMMU J231503-585607

The final masks have been added, completing the Phase 2 preperation for this run:
XMMU J002210-483634
XMMU J000216-355633
