Estimated Total Execution Time (hours, including overheads)

• 05:05:48

General Description

• Allocated time:  These are PARSEC GTO observations. We changed the OBs
   upon request of ESO, now including dedicated sky obs. We have nominally 4:56h left
   for P78. Due to the large acquision overheads and limitation of DITs to 300s, 600s
   and 900s our execution time exceeds this by 10 minutes to prepare a sensible and
   homegeneous set of OBs, which we hope is ok.

      point source QSO  
  
  None of the targets or guide stars is brighter than 10th mag in the NIR. All magnitudes
   are   point source magnitudes, except for the guide star of PG1115, which are two
   point sources at  0.5" distance.  
  
  ----------- 
  Goal:  We want to observe 4 QSOs, redshift 1.5 to 2.3, three of them gravitationally
   lensed. Goal is to take H or K band spectra including Halpha, to detect extended
   Halpha in emission from the surrounding  galaxy. This narrow Halpha emission line
   is expected to show velocity structures which we want to use to estimate a dynamical
   mass of the galaxy. We are only interested in Halpha and the velocity, no line fluxes
   or ratios are to be determined.  The continuum of the QSO host galaxy is likely
   too faint to be detected, so only Halpha (broad and narrow components) and possibly
   a few other emission lines will be seen.  The non-lensed QSO has a TT star at 9.7"
   distance, the 3 lensed QSOs have to be TT guided on parts of themselves, for one
   of them (HE1104) the gioding and spectroscopy position are fully identical. For
   the other two (HE0047 and PG1115) there center of spectroscopy is the center of
   the system, while guiding will be done on one the brightest component.  Two of the
   QSOs (PG1115 and HE0047) have as the brightest component R~16.5-17, so just at the
   edge of the permitted TT "star" limit. Since there are fainter components nearby,
   the TT sensor could/needs to be windowed around this brightest component. The underlying
   host galaxy and lensing galaxy contribute only very little flux to the system. 
   
  
  -------- 
  Coordinate precision:  While the absolute coordinates could be off by ~1", the relative
   positions between guide star and target are always correct.  
  
  --------- Priorities: 
  Each target has 1 OB, all with the same priority

Waiver Requests

• 078.B-0280A.01.WAV was granted (execution of OBs longer than 1h), approved
   4 Aug 2006

Critical Observing Condition Constraints

• We need as small a PSF as possible to remove the quasar light from the
   underlying emission line part. Also, we need as much depth as possible, with a decent
   sky line subtraction. 
  Therefore: <0.6" seeing, clear sky, not too high airmass (<1.8), some moon
   distance for the faint grav. lenses (50 deg and 0.7 moon phase).
