General Description

• JHKs autojitter imaging of planetary microlensing events in progress.
  
  Once a planetary microlensing event candidate has been identified
  prompt high resolution images will establish a first reference epoch 
  of JHKs data while the event is in progress and the 
  microlensing source is still magnified.  
  
  Together with a second epoch/trigger taken later at different magnification
  of the target we will be able to separate the event
  from unrelated background sources in the crowded target Bulge fields 
  and be able to put strong constraints on the mass of the planet candidate
  and its host star (the lens) and their physical separation. 
  
  We strongly PREFER the use of the LASER GUIDE STAR and corresponding OBs 
  are maked with -LGS- in their names.  If however the laser is not
  operational and unlikely to be available within the given
  validity time window of a trigger then natural guide stars can
  be used as backup (marked with -NGS- in OB name).

Waiver Requests

• Waiver Request 081.C-0429A.01.WAV granted
  
  Dear Daniel,
  
  Also this waiver request to have OBs of duration 1.5-2h was
  granted, with the usual restriction that an OB will not
  be repeated or aborted if conditions degrade below constraints
  after the first hour.
  
  As mentioned in the reply regarding program 425(A), it is
  important to attempt to optimize the execution time also
  with the possibility in mind that it is possible that
  a part of the OB is executed outside constraint.
  And as a last point: Very long OBs are difficult to schedule,
  particularly if the airmass constraint is stringent with a
  target low in the sky etc.
  
  I'm looking forward to receiving your Phase2 material,
  
  Cheers,
  Sabine

Critical Observing Condition Constraints

• Good seeing and good sky transparency are beneficial for the science.
  
  Since however a fast execution of the first epoch (at considerable magnification)
  is important too, clear sky is a sufficient weather condition.

Time-Critical Aspects

• A prompt execution of the OB after the trigger is desirable.
  Depending on the Einstein time scale of the event the valid time window 
  will be given in the trigger.

Special Execution Requirements

• It is desirable to have a photometric standard taken close in time
  to the science OB.

Special Calibration Information

• OBs are in standard DCR-HD readout mode according to the supported Calibration
   plan.
  The science/photometric accuracy will benefit however if the standard can be taken
   
  close in time to the science OB.

ToO Information

• Finding charts will be submitted with the trigger.
