General Description

One object, a set of ISAAC medium resolution spectra mapping the J-band.
Target has J about 15.5, but variable at the level 0.2 mag. Search for
emission lines or signatures of the companion star in a B-type binary.

There is only one field of view for this program, and the brightest star
there has a DENIS J magnitude of about 12.6.

Justification for photometric time: The length of our exposures were based
on simulations considering photometric conditions, so non-photometric
conditions should require more observing time. There is no security that
the program is sucessfull if we relax this condition. Expected signal to
noise ratio and spectral resolution for every spectra rest on the assumption
that the sky is photometric.

Critical Observing Condition Constraints

Time-Critical Aspects

The optimum should be get the OBs separated by 1 or 2 nights (1 OB per
 night) during a period of 7 or 14 days. This way we have a chance of mapping the
 orbital motion of the binary by studying the RVs of the lines during the 7-day orbital
 period, which should be a pretty nice by-product for this project.
