General Description

J-band spectroscopy of YSOs in a young cluster. The slit positions
have been chosen to cover the most important objects; nevertheless we
aim to have as many objects on the slit as possible.

We are aware of the fact that we did not ask for special
calibration. Nevertheless we would be extremely happy if the telluric
standard stars would be early main sequence stars, and if they would
be observed at similar airmasses.

Comments on revision:
I used the brightenss limits of 17-18m for acquisition in JHK and the ETC
to compute brightness limits in the SZ-band and the NB_1.06 filter. (e.g.
SZ: 15.5-16.5 and NB_1.06: 14.5-15.5)

Unfortunately that computation was not possible for the filter combination
NB_1.06+NB_1.08 because that is not an option in the ETC. Therefore I had
to estimate brightenss limits of 13-14.

Seven OBs make use of the NB_1.06+NB_1.08 filter combination. I changed
only 5 of them to offset acquisition because the reference targets in the
other two OBs should be bright enough (~13.8mag). If that is still to
faint I will of course change these OBs too.

Latest changes:
I have modified the critical OBs according to the recomendation of the 
observer i.e. Js+NB_1.08 and DIT=5sec.
