General Description

• Our program: 'Quantifying star formation at high spatial resolution: Q-band
   observations of nearby starburst galaxies' (078.B-017(A),(B) and (C)) aims to use
   VISIR Q-band observations for a detailed study of embedded star-forming regions
   in nearby starburst galaxies. The Q-band imaging and spectroscopy covering the [SIII]
   emission line at 18.71 micron complement VISIR N-band data already obtained for
   these objects. Together they will give detailed information on the effective temperature
   of the radiation field, the extent of emission line regions and excitation of HII
   regions.
  
  NGC7552 MR Q-band spectroscopy of the [SIII] line: two sources are observed simultaneously
   in an on-slit chopping/nodding setup (see finding chart for config). Parameters
   are identical as previously in N-band spectroscopic obervations. Second source might
   be too weak to be observed in result single OB. For acquisition focus on brightest
   source, which has to be displaced approximately  17 left of slit centre (column
   111).
  
  Finding charts uses VISIR Q-filter image for NGC7552. For IC1623 a NIR image from
   the ESO Digitized SKy Cat is used, however blind preset is applied, so there shouldn't
   be a problem with acquisition.

Waiver Requests

• A waiver request to create OBs that take longer than 1 hour to execute
  has been approved for this programs. The request was submitted
  July 18.  Approval was received Junly 19 from Mario van den Ancker.

Critical Observing Condition Constraints

• None other than observing constraints given in OBs.

Time-Critical Aspects

• None

Special Execution Requirements

Special Calibration Information

• Part of this program consists of MR spectroscopy around the [SIII]
  line @ 18.71 micron. Since no standard calibrations are performed for
  MR spec, OBs for calibration observations are created (see all OBs
  starting with CAL). In general for these MR spectroscopy we would like
  to obtain a standard star at comparable airmass per science
  observation. 
  
  Young type stars are generally too weak in the Q-band, so
  K-/M-band stars are selected. IF THE STANDARD STAR CHOSEN IS NOT AT
  COMPARABLE AIRMASS AS THE SCIENCE OBSERVATIONS, PLEASE CHANGE TO
  ANOTHER STAR THAT DOES MEET THIS REQUIREMENT (K-/M-band brighter approx 8Jy in
  Q2). The standard star chosen in the CAL OBs should be suitable for most of
  the possible observation times, but please be so kind to check.
