Estimated Total Execution Time (hours, including overheads)
General Description
* Science objectives: We want to obtain a spectrum of the candidate weak
emission line quasar HE0141-3932 (redshift z=1.8). This spectrum should be compared
to a synthetic quasar spectrum to unveil slope differences and other spectral differences
when compared to normal quasars. In addition, the low ionization emission lines
(MgII 2798, H gamma 4340) will be used to measure the accretion rate and disentangle
between different scenarii that explain the nature of weak emission line quasars.
Finally, narrow quasar emission lines will be searched for.
* Important Observational aspects: To drive this science we need high S/N spectra
(S/N ~ 100/spectral resolution element). We also need to achieve achieve accurate
sky subtraction, a proper response curve and differential extinction correction,
proper correction for telluric lines in the Near-Infra-Red.
Target Estimated Mag: R=15.8 (might be variable)

Critical Observing Condition Constraints
Time-Critical Aspects
Special Execution Requirements
Special Calibration Information
No extra calibration
Normal calibration, including flat field, bias with high gain and bin 1x2 + arc
lamps
Standard star + Telluric star obtained during normal operation are enough. We prefer
hot telluric star.

Do all your OBs comply with the instrument-specific requirements listed
on the instrument-specific Phase 2 web page ?
Do all your finding charts comply with both the general and instrument-specific
Phase 2 Web Pages ?
If you submitted OBs for standard stars, did you specify the magnitude
and spectral type of all standard stars in the OBs ?
Have you specified the S/N ratio at given wavelength in the User Comments
field of each OB?
Have you included OBs for any calibrations that you need but which are
not part of the Calibration Plan ?
If you are observing Moving Targets, have you attached suitable ephemeris
files to your OBs?
If you have preferences which OBs should be executed first, did you make
use of the User Priority field in the OBs ?
If this is a run that requires coordinated observations with other facilities,
did you give proper instructions in the Time-Critical Aspects Section ?
