Principal Investigator Email Address

Estimated Total Execution Time (hours, including overheads)

• 6

General Description

• Low resolution N-band spectroscopy in the 4 wavelength settings 8.5, 9.8,
   11.4, 12.4 of the galactic nucleus of NGC 4579 to investigate its complex nature.
  
  Concerning the finding charts: The source is very faint ant will only be visible
   on long time exposures. It will appear pointlike and should be the brightest source
   in the field of view.

Waiver Requests

• Waiver Request 083.B-0536B.01 
  -submitted at 26.01.09 and approved at approved at the 27.01.09.
  -reason: All four spectroscopic OBs exceed 1 hour execution time (1:18:00).

Critical Observing Condition Constraints

• For the OBs with the wavelength settings 12.2 and 8.5 the constraints
   are most critical.

Time-Critical Aspects

• none

Special Execution Requirements

• The telescope guide star is provided in the OB. It fulfills the constraints
   given in the guidecam manual of VISIR and is chosen from the UCAC2-catalog. As far
   as possible, the telescope operator should use it. For some objects there are 1
   or 2 alternative provided guide stars given in the user comments of the according
   OB. So please write down in the README notes which guide star was used so that all
   subsequent OBs use the same guide star. The telescope operator should check that
   the guide star is not changed automatically by the TCS after, for example, an uncompleted
   offset. This is necessary to be able to combine data from different OBs.

Special Calibration Information

• To each spectroscopic science OB belongs one calibration OB (prefix CAL_)
   which needs to be executed contiguously. The airmass should not differ more than
   0.2 between calibration and science OB. Otherwise please choose another suitable
   calibration star for the VISIR imaging filters which fulfills this constraint.

If this is a pre-imaging run, did you select PRE-IMAGING for the Observing
 Category for each Observing Template ?

• N/A

Do all your finding charts comply with both the general and instrument-specific
 Phase 2 Web Pages ?

• YES

If you submitted OBs for standard stars, did you specify the magnitude
 and spectral type of all standard stars in the OBs ?

• N/A

Have you included OBs for any calibrations that you need but which are
 not part of the Calibration Plan ?

• YES

If you are observing Moving Targets, have you attached suitable ephemeris
 files to your OBs?

• N/A

If you have preferences which OBs should be executed first, did you make
 use of the User Priority field in the OBs ?

• YES

If this is a run that requires coordinated observations with other facilities,
 did you give proper instructions in the Time-Critical Aspects Section ?

• N/A

If the provided finding chart is at a different wavelength than the observations,
 did you clearly describe in the README file how to identify the target?

• YES

 r=5arcmin around the science target?

• YES
