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.
  
  M83  MR Q-band spectroscopy of the [SIII] line: several sources are oberved simultaneously
   in an on-slit chopping/nodding setup (see finding chart for config). Parameters
   are identical as previously in
  N-band spectroscopic obervations. Source has a rather complicated morphology, for
   acquisition focus on brightest source, which has to be displaced approximately 28
   pix left of slit centre (column 100).
  
  Both targets observed with VISIR before, finding guide star was not a problem.

Waiver Requests

• A waiver request to create OBs that take longer than 1 hour to execute
   have been approved for this program. The request was submitted July 18.  Approval
   was received Junly 19 from Mario van den Ancker.
  
  Furthermore a change request to use the imaging filters Q1 and Q3 has been approved
   (in the original proposal only Q2 was requested). Request submitted July 31, approval
   received July 31 from Mario van den Ancker.

Critical Observing Condition Constraints

• NOne but the constraints as given in the OBs.

Time-Critical Aspects

• None

Special Execution Requirements

• Three calibration OBs for MR Q-band spectroscopy; one standard star should
   be observed before science target and two afterwards (CAL_M83_Qspec_1 before, and
   CAL_M83_Qspec_2 and CAL_M83_Qspec_3 after science OB, see special calibration 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 (brighter approx 8Jy in Q2). The standard stars chosen in the OBs
   should be suitable for most of the possible observation times, but please be so
   kind to check.
  
  One standard should be observed before science target and two afterwards (CAL_M83_Qspec_1
   before, and CAL_M83_Qspec_2 and CAL_M83_Qspec_3 after science OB)
