There were two tiles assigned to the Clauds Cosmos field, such that the 5000 fibers picked up a
different set of targets on each tile at the same location.

We observed for 6 and 6.5 hrs in real time on each.  When weighted by conditions, this comes out to 
be ~6hrs on each.  It is highly unlikely there will be further opportunities to pick up more time, or more
fields (over the next five years). 

On the two tiles, in terms of targets, we expect:

DESILBG_TMG_FINAL      931   613
DESILBG_BXU_FINAL     1221  1721
DESILBG_G_FINAL        842  1128

a total of 6456 targets.   At the height of Survey Validation, when these were being observed, we continued
to be working through calibrating the focal plane.  As such, not all of these will have had a fiber placed 
successfully.  I haven't yet done the latest book keeping on that.
