Estimated Total Execution Time (hours, including overheads)

• 16:00:00.000

General Description

• This is a simple run concerning a single object. The main point is obtaining
   a high SNR, while having high spectral resolution. We have defined two OB's that
   differ only in the setting for the red arm, to cover a large wavelength range in
   the red. The chosen blue setting, 346 nm, includes the H2 absorption lines, which
   are the main focus of this observation run and require the highest S/N possible
   and careful wavelength calibration.
  
  So there are 2 different OB's, using 2 different dichroics (all other settings are
   the same). For each OB there are 8 identical copies, giving 16 OB's in total, of
   1 hour execution time each.

Waiver Requests

• No Waiver Request was submitted

Critical Observing Condition Constraints

• Our observing condition constraints are the same for all OB's. 
  
  Seeing: better than 1.0''
  Airmass: below 1.4
  Sky transparency: clear
  Moon: grey time

Time-Critical Aspects

• There are no time-critical aspects

Special Execution Requirements

• Please make sure that for both settings there is an equal amount of observation
   time. So, execute OB's for the 2 settings alternatingly just in case the entire
   run will not be completed.

Special Calibration Information

• Attached wavelength calibrations are very important for our science goals,
   especially in the blue, and are therefore included in all OB's. Only for the 760
   red arm setting no attached wavelength calibration exposure is included, to avoid
   ThAr remnants on the CCD chip. Make sure that the attached wavelength calibration
   in the blue is carried out for ALL exposures (also when for the red arm the 760
   setting is used). The 760 ThAr calibration must ofcourse be executed as part of
   the standard Calibration Plan.
  
  Please make sure to check and adapt the attached wavelength calibration exposure
   times to the exposure times used currently, depending on lamp age etc. (blue:2x2
   binning and 0.8" slit, red: 1x1 binning, 0.7" slit) (except for the 760 ThAr exposure
   time, set to 0s.)
