Estimated Total Execution Time (hours, including overheads)

• 10.04h

General Description

• The purpose of this observing run is to obtain circular spectropolarimetry
   of the black hole binary Cyg X-1 at 7 epochs distributed over the orbital period
   of 5.6 days. Each OB (Cyg_X_1_phase1... Cyg_X_1_phase7) has to 
  be executed on specific nights to obtain good phase coverage. It is important to
   
  obtain these observations as close as possible to the quasi-simultaneous observations
   
  scheduled on other telescopes: May 20-23 on Korean BOAO 1.8m telescope, May 17-27
   and June 10-29 on Peak Terskol 2m telescope.
  The list of suitable nights for each OB is given in the section "Time-Critical Aspects".

Waiver Requests

• We submitted a Waiver Request 381.D-0138A.01.WAV on January 17 to use
   the non-standard readout mode 200kHz,1x1,low, and for the length of the OB of 1h26m.
   The request was approved 
  on January 22.

Special Execution Requirements

• Each OB should be executed on specific dates. Suitable dates are given
   in the section 
  Time-Critical Aspects. If for any reason any of the seven OBs is not executed by
   the end 
  of July, we will submit a list of suitable phases for August and September.

Special Calibration Information

• For the reduction we just need one ARC frame for each observations and
   the FLAT frame
  should be taken only once.
