General Description
-------------------

This programs aims at observing young star clusters and star forming
regions in nearby spiral galaxies. Our targets are NGC7793 and M83. 
These galaxies are at similar distances, so the observing strategy 
should be identical.

We want observations in Y, J, H, K and Br_gamma, with on target
exposure times (per galaxy):

Y,J,H,K: 10 min in each band (5 min target + 5 min sky)
Br_gamma: 20 min (10 min target + 10 min sky)

Observations should be carried out as sequences of B-T-T-B-T-T-B ..
where 'B' are Background fields and 'T' are target fields. The single
'B' and 'T' observations should have identical exposure times of
NDIT= 10 sec and DIT= 6 for each filter and each target.

For the sky subtraction we have selected empty regions located
at some distances from the galaxies. In order to avoid having a
bright star in the field, we would prefer to use fixed offsets:

NGC7793: 15 arcmin away from the target exactly to the North-East
direction (i.e. -15, +15)

M83: 18 arcmin to the West and 6 arcmin to the North at the same
time (i.e. +18,+6)


For the dithering we would like to use 40" jitter box - the same
for all the targets.

We aim for a total of 30 min of integration time on-target and 30 min
on sky for each galaxy in a seeing of 0.80" or better.
