Just a few more details concerning the table I sent:

e = early-type, i.e., no extinction
s = late-type, for which I assumed E(B-V)=0.1

NJ = NIC2/F110W
NH = NIC2/F160W (low-sky orientation)

Furthermore, I used the following orbit to exposure time
conversion:

# time
-- - ----
NJ 1 2048s
NJ 2 4096s
NH 1 1845s
NH 2 3690s

Finally (as one can see) I've assumed
for a E/S0 host, 5 total orbits for the lightcurve before final refs
for a late-type host, 12 total orbits for the lightcurve before final refs

I'm set up to quickly do SNR calculations for any other orbit scenario.
