General Description

• We plan to obtain spectroastrometric observations of the nucleus of the
   Circinus galaxy. We will obtain K band spectra centered at the observed wavelenght
   of the Br gamma line (2.170nm). Observations should be obtained with the slit centered
   on the bright unresolved K band nucleus and with 3 different slit position angles.
   
  Please, note that in contrast with "standard" spectroastrometric observations we
   do not require flipping the slit by 180 deg.

Waiver Requests

• A waiver request to use the free wavelength setting at 2170 nm was submitted
   on 28/01/2009 and granted on 02/02/2009 by Michael Hilker (ESO User Support Department).

Critical Observing Condition Constraints

• None.

Time-Critical Aspects

• None.

Special Execution Requirements

• None.

Special Calibration Information

• For each object OB (named as Circinus_Galaxy_PA*) we require one telluric
   standard OB (named as CAL_Circinus_Galaxy_PA* where * is the same as the object
   OB to which it is associated).
  The telluric standard OB should be executed shortly after/before the associated
   science OB.
  All telluric standard OBs have the same exposure setting and should be performed
   in the "ELEV" mode (ie slit along parallactic angle).
  The telluric standard is a O7/O8 star with K=7.2

ToO Information

• N/A

ToO Activators List

• N/A

Do the README file and the instrument comments of the telluric stars
 OBs include the required S/N/pixel of the spectrum of the telluric star, its spectral
 type and allowed spectral range?

• YES

Do any OBs include wavelength or flatfield calibrations?

• NO

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

• N/A

If the slit viewer guide star is different from the target, are the RA
 and DEC offsets accurate to within 0.05 arcsec and do they take into account the
 relative proper motion between the two objects?

• N/A

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