Programme Description
=====================

General Overview
----------------

This observing program consist in a spectroscopic monitoring of the Halpha line
in z~2 quasars: the aim is to obtain lightcurves of both continuum and Halpha
line. Low and Medium resolution spectra of the quasar at 2.2 micron will be
obtained.  Since the observations can be performed under non-photometric
conditions, we need a way to perform a relative flux calibration: we then
requested an image of the field with the Ks filter which will be compared with
the images associated with the low resolution spectra taken at different
epochs. By comparing the fluxes of several objects in the field we can rescale
the low resolution spectra. It is VERY important that the image is taken
shortly after/before the object spectrum.  The medium resolution spectrum,
sampling the core of the line, will be rescaled to the low resolution spectrum.
Also a medium resolution spectrum of a telluric standard (B star) is requested:
also this should be obtained shortly after/before the object spectrum in order
to properly cancel the atmospheric absorption features.  SINCE VARIABILITY
MIGHT CHANGE THE HALPHA LINE IT IS HIGHLY IMPORTANT THAT THE MEDIUM RESOLUTION
THE LOW RESOLUTION SPECTRUM BE TAKEN WITHIN 1-2 DAYS FROM EACH OTHER.

This program is associated with 68-B-0197(A),(B),(C),(D),(E)

Time Critical Aspects
---------------------

All observing blocks should be executed in March 2002.  For each object of
the project we plan to obtain a spectra at a ~1 month interval (see associated
68-B-0197(A),(B),(C),(D),(E)).  All objects should have been
observed in February:
please observe the
objects after ~1 month with respect to the February observation. If all OBs are
executed around full moon this should provide the adequate time intervals for
this project.

SINCE VARIABILITY MIGHT CHANGE THE HALPHA LINE IT IS HIGHLY IMPORTANT THAT THE
MEDIUM RESOLUTION THE LOW RESOLUTION SPECTRUM BE TAKEN WITHIN 1-2 DAYS FROM
EACH OTHER.


Special Calibration Information
-------------------------------

We have requested night time spectroscopic flat fields to correct for 
the "non-reproducibility effects" present with high S/N (>100) data
such as those of the spectroscopic standard star.
These flats are suggested in the "P2PP: ISAAC Information" manual.


ToO Information

This is not a ToO programme.

OB Compliance Checks
====================

Y = Yes, N = No, NA = Not Applicable

Do all your OBs comply with the instrument specific requirements 
listed on the instrument specific Phase 2 Web pages [Y/N/NA]? Y

Do all your FORS OBs use only the allowed detector read-out modes 
listed on the FORS1/FORS2 Phase 2 Web pages? [Y/N/NA] NA

Do all your FORS MOS/LSS OBs contain the mandatory "through-slit 
image" template? [Y/N/NA]? NA

Do all your UVES OBs use only the allowed templates listed on the 
UVES Phase 2 Web pages [Y/N/NA]? NA

If you submitted OBs for standard stars, did you specify the magnitude and 
spectral type of all standard stars [Y/N/NA]? Y

[ISAAC only] Are ALL the objects in your field-of-view fainter than the 
magnitude limits specified on the ISAAC Phase 2 Web page [Y/N/NA]? Y

[ISAAC only] If you submitted OBs for standard stars, did you
use the provided StandardStar templates? [Y/N/NA]? Y

If you answered "NO" to any of these questions, please revise your 
OBs *before* submission.
