Here are our expected photometric errors in i775 and z850 - as Henk
knew, the 4:1 exposure ratio for z850:i775 yields comparable errors at
each AB mag interval. these are based on scaling our Lynx (z=1.27)
mosaic exposures to the exptimes we will have in our co-added data. I
am modifying the cluster obs reqs section accordingly and making the
CMR slope/scatter measurements the main drivers.
