General Description

• OVERVIEW:
  The aim of the program is to identify the companion star to a binary MSP in the
   Galactic field.
  
  OCCULTING MASK POSITIONING:
  Since the companion star is expected to be very faint, the brightest stars close
   to the MSP nominal position (and few other bright stars within the overall FOV)
   have been masked with the FORS occulting masks.
  Hence, a very precise positioning of the occulting masks (expecially #10 and #11)
   is crucial for the success of the program.
  
  OB ORGANIZATION:
  The observations will be perfomed in three filters (b_high, v_high and I_BESS).
  
  Since we use the 200kHz,1x1,low detector mode (see the Waiver request), we have
   prepared 2 calibration OBs to be perfomed contigously under photometric conditions:
  CAL_PG1323 is the calibration OB to be perfomed on the PG1323 Stetson standard star
   field
  CAL_mspfield is the calibration OB to be perfomed on the science FOV
  
  The remaining observations are organized in 7 additional OBs, which do not require
   photometric conditions, but must be executed with dark moon and seeing of 0.8".
   Each OB lasts less than 1h:
  mspfield_b1, _b2, _b3 are 3 OBs for the science observations in the b_high filter
  mspfield_v1, _v2 are 2 OBs for the science observations in the v_high filter
  mspfield_i1, _i2  are 2 OBs for the science observations in the I_BESS filter
  
  
  FINDING CHARTS:
  The FC is the same for each science run.

Waiver Requests

• Waiver ID: 383.D-0406A.02.WAV
  
  We have submitted a waiver request for using non-standard read out mode (200kHz,1x1,low)
   with SR and occulting mask in order to better control the saturation of the brightest
   stars.
  On 2009, February the 12th, the waiver was granted.

Critical Observing Condition Constraints

• none

Time-Critical Aspects

• For calibration purposes, we request the two calibration OBs (CAL_PG1323
   and CAL_mspfield) to be exectuted contigously.

Special Execution Requirements

• In order to enhance the detection probability, the execution priority
   is highest (pr=1) for the 3 OBs in the b_high filter, intermediate (pr=2) for the
   2 OBs in the v_high filter, and lower (pr=3) for the 2 OBs in the I_BESS filter.

Special Calibration Information

• Since the use the 200kHz,1x1,low detector mode is not part of the standard
   FORS calibration plan, we have submitted 2 calibration OBs:
  CAL_PG1323 is the calibration OB to be perfomed on the PG1323 Stetson standard star
   field
  CAL_mspfield is the calibration OB to be perfomed on the science FOV
  
  These OBs have to be perfomed contigously and under photometric conditions, while
   the seeing and lunar illumination constraints have been relaxed in this case (with
   respect to the science run).
  
  Since the reference calibration field (PG1323 Stetson Standard Field) is one of
   the FORS Standard Field, we do not provide the magnitude and spectral type list,
   nor the FC.
