Estimated Total Execution Time (hours, including overheads)

• 25 hours

General Description

• Photometric follow-up of stars harbouring planets: observation of the
   planetary transit to accurately measure the planet radius (typically 1% of the star
   flux) and constrain the orbit ephemeris.
  
  This is thus a time critical programme (see "Time Critical Aspects" and time spans
   in OBs)

Waiver Requests

• The time critical aspect of these observations drives the two following
   waiver requests:
  -the OBs last more than one hour
  -several OBs should be executed consecutively
  These request were approved on Feb. 26th.

Critical Observing Condition Constraints

• No critical constraints on the conditions. 
  The execution period is the only constraint

Time-Critical Aspects

• The observations must be conducted at the following time spans:
  
  OGLE-113:
  observation on Apr 04th from 0:15 to 05:15 UT
  AND
  observation on Apr 14th from 1:00 to 06:00 UT
  
  OGLE-132:
  observation on Apr 20th from 0:30 to 05:30 UT
  
  OGLE-56:
  observation on June 15th from 1:45 to 04:45 UT (stop before zenith crossing)
  AND
  observation on July 02nd from 2:15 to 03:45 UT (stop before zenith crossing)
  AND
  observation on July 02nd from 4:15 to 05:45 UT (start after zenith crossing)
  AND
  observation on July 06th from 23:00 to July 7th 02:30 UT (please start as early
   as possible after twilight)
  
  Note 1 (obvious, but may help): the dates are in UT (also in the OB name), after
   0:00. A date D usually corresponds to a night starting at D-1.

Special Execution Requirements

• Acquisition: the star should be put next to the pixel given in the acq
   template (not very precisely),  because it seems to be a clean piece of the detector.
  
  Execution: Please have a check for saturation on the target, if the seeing is very
   good. 
  
  Target coordinates:
  OGLE-113 RA_2000=10:52:24.40  DEC_2000=-61:26:48.5 
  OGLE-132 RA_2000=10:50:34.72  DEC_2000=-61:57:25.9 
  OGLE-56  RA_2000=17:56:35.51  DEC_2000=-29:32:21.2
  
  Execution sequence: for each observing dates ("Time-critical aspects") there are
   several OBs to be executed consecutively (because P2PP does not allow for more than
   100 exposures in a row). Start with number 1 which has Preset Flag TRUE and then
   continue with 2 and (sometimes) 3 (no preset, or preset to be skipped in BOB). If
   the star drifts on the detector by more than 20 pixels, please redo the acquisition
   during the sequence. Otherwise the sequence should not be interrupted (ie choose
   a guide star allowing long adaptor times). Crossing of the zenith is avoided in
   the time interval definition.
