Estimated Total Execution Time (hours, including overheads)

• 04:00:21

General Description

• Three OB's (N2997LR_JH, N2997LR_K, N2997MR_K) are used to observed the
   knots.  As they are strongly
  embedded in dust lanes, all acquisition frames are done in Ks.  The brights stars
   in the field are
  star B (K=12.7) and star C (K=12.7) while star S (K=9.5) is 2' from the center of
   the field.
  Star A (K=14.0) is used for general reference.  The knots have integrated magnitudes
   in the range
  of K = 16-18.  The objective is to include as many of the knots (Ka, Kb, ...) within
   the 2" slit.
  Two strategies may be used:
    1) If the knots are visible on the acquisition frame, the slit angle should be
   adjusted to
       include as many knots as possible but still having star A partly in the slit
   close to
        pixel (519,460) to avoid the dust patch on the detector.
    2) If the knots cannot be clearly identified, star A is placed on pixel (519,460)
   and the pre-defined
       slit angle of -107.6 is used.
  The approximate position of the center of the 2" slit is indicated on the detailed
   finding chart.
  
  'CAL RVstd' provides a RV template spectrum for the cross-correlation with N2997MR_K
  
  N2997MR_K_Cent provides are velocity reference to the center of NGC 2997

Waiver Requests

• WaiverID:  075.B-0579A.01 - execution time of OB 'N2997MR_K' exceeds 1
   hour (71 min)
  WaiverID:  075.B-0579A.02 - two central wavelength settings in OB 'N2997LR_JH'

Special Execution Requirements

• None

Special Calibration Information

• The OB 'CAL RVstd' will be used as the reference spectrum for determining
   the radial velocity (using
  cross-correlation) of the spectra obtained by OB 'N2997MR_K'.  Thus, it should be
   take in the same
  seeing conditions.  Even thick clouds are acceptable as it magnitude is K=5.4.
  
  For Tellerium Standards, B-type star are prefered.
