Estimated Total Execution Time (hours, including overheads)

• 12

General Description

• This is a monitoring program that should be executed (if possible) once
  every two weeks.
  
  The observation consists of V-band imaging in staring mode (i.e. no jitter).
  The target is the nebula around RZ Sgr. The star itself should be put in the
  gap between the CCDs, and 7 times 30-sec exposures should be taken per epoch.
  Additionally, one of the 'calstars' OB should be executed 
  (no particular preference, but a different one for each epoch): this star
  should also be centred on the CCD gap, followed by a single 300-sec exposure.
  Finally one of the 'blanksky' OBs should be executed. These OBs all have the 
  same field.
  
  The goal of the standard star is to measure the scattered light from the star
  in the image, and the blank sky is done to correct for diffuse scattered light
  (Moon light). All selected fields are within a few degrees of each other
  
  Observations should be taken during dark or grey sky. Photometric conditions not
  required but sky brightness should not be too high, i.e. no Moon-illuminated
  cirrus please! Seeing upto 2 arcsec can be tolerated
  
  So the sequence per epoch should be
   1. RZ_Sgr-
   2. RZ_Sgr_calstar-
   3. RZ_Sgr_blanksky-
   total time per epoch up to 1 hour

Waiver Requests

• No Waiver Request was submitted

Critical Observing Condition Constraints

• Observations should not be taken under too bright sky conditions.
  (i.e. no cirrus illuminated by a bright Moon). Grey/dark
  preferred; full Moon needs to be avoided.
  
  Seeing not critical.

Time-Critical Aspects

• One epoch should be taken approximately every two weeks. Precise timing
  is not too critical as long as the epochs are spaced out over the semester.
  Minimum sampling is once per month.

Special Execution Requirements

• Every observation/epoch consists of three OBs:
   RZSgr (science object), calstar, and blanksky.
  These should be taken under reasonably similar
  conditions but do not need to be fully consecutive.
  The 'blanksky' is important when the sky is not dark,
  during dark time this may be dropped if short of time.
