Estimated Total Execution Time (hours, including overheads)

• 1 hour 41 minutes

General Description

• Spectroscopy of bright (1 < V <3) stars.  ND2/3 filter used for
   acquisition; no finding charts provided since these objects are blindingly bright.
    However, note that alpha Cru and gamma2 vel are binaries, if the secondary has
   crept into the field of view, our science targets are always the brighter of the
   pair.  All OBs can be done during the end of twilight.  Two set-ups per target (blue,
   dic) best executed consecutively to avoid excess overheads.
  
  S/N estimates in user comments assume good conditions i.e. seeing=0.8" and airmass=1.2.
  S/N degrades quite rapidly in poorer conditions due to the narrow slit (see constraint
   set for limiting tolerances).

Waiver Requests

• Additional daytime flats submitted

Critical Observing Condition Constraints

• Please don't attempt in very good (<0.7") seeing, or stars will saturate.

Time-Critical Aspects

• N/A

Special Execution Requirements

• Some orders may saturate, that's OK, since we're interested in only the
   following wavelengths:
  
  Blue setting: 330nm (approx 1/3 of the way up the CCD from bluest order)
  Dic1 390 setting: 390nm (middle of CCD)
  Dic1 580 setting: 590nm (2nd bluest order on red CCD)

Special Calibration Information

• Final science spectra will have S/N ~400-500, so flat-fields must have
   high S/N.  I would therefore like to request extra flats to be taken during the
   daytime (cleared with Francesca Primas@USD and PSO).  Please execute the following
   extra flatfields by changing the number produced by calobbuild, consecutive to nights
   when science OBs have been executed if possible.
  
  If any science OBs named *_blue were executed, please take *at least* 20 extra D2
   flats (40 if the daytime operations schedule permits) for the B346 setting.  I estimate
   that 20 flats will add 1 hour to the calibration set.
  
  If any science OBs named *_dic were executed, please take 40 (a minimum of 20 could
   be tolerated) extra flats for the 390+580 setting.  I estimate 40 flats will add
   45 minutes to the calibration set.
