Estimated Total Execution Time (hours, including overheads)

• 20.4

General Description

• This is a straightforward spectroscopic program with usually one OB 
  per target (exception CHXR74) consisting of two back-to-back exposures
  in order to measure precise radial velocities.
  
  The observations are ideally carried out in January to allow
  a time offset of at least 20 days to observations of partly 
  the same targets in run B.
  
  The 3 OBs for CHXR74 (ob-chxr74-1, ob-chxr74-2, ob-chxr74-3)
  can be carried out anytime, but there should be a timely separation
  between these 3 OBs of a few (e.g. 2-3) days.
  
  In the OB ob-Hn21 a rotation is applied to cover two targets in the slit
  as indicated on the finding charts.
  
  The total duration of 7 OBs of this run exceed 1 hour (see waiver)
  but none exceeds 2 hours.

Waiver Requests

• Waiver Request 082.C-0023A.01:
  
  a waiver was granted to exceed the total duration of 1 hour per OB
  for 7 OBs of this run.

Critical Observing Condition Constraints

• The OBs can be executed under a seeing of 2" and bright time. 
  Thin cirrus clouds (inducing absorption up to 0.2mag) may be present.  
  The airmass should be below 2.

Time-Critical Aspects

• The observations are ideally carried out in January to allow
  a time offset of at least 20 days to observations of partly 
  the same targets in run B.
  
  The 3 OBs for CHXR74 (ob-chxr74-1, ob-chxr74-2, ob-chxr74-3)
  can be carried out anytime, but there should be a timely separation
  between these 3 OBs of a few (e.g. 2-3) days.

Special Execution Requirements

• N/A

Special Calibration Information

• wavelength calibration (ThAr) is needed on the same day with exactly the
   same settings
  as the science OB for readout , slit and central wavelength.

ToO Information

• N/A

ToO Activators List

• N/A

Do all your OBs comply with the instrument-specific requirements listed
 on the instrument-specific Phase 2 web page ?

• YES

 and spectral type of all standard stars in the OBs ?

• N/A

Have you specified the S/N ratio at given wavelength in the User Comments
 field of each OB?

 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
