General Description

• JHKs autojitter imaging of 3 planetary microlensing event candidates.
  
  This is the follow-up 2nd imaging epoch of 3 planetary microlensing  
  discovered and observed with NACO in Period 79 while the events were still
  in progress. The events are now at baseline, i.e. the lensing effect has terminated.
    
  
  The magnification gradient and therefore the brightness difference between epoch
   1 
  (period 79 run) and epoch 2 (this run) will allow us to separate the microlensing
   event 
  from unrelated background sources and so indirectly enable a measurement of the
   brightness of
  the lens star, the planetary host star. "Indirect" because the lens and source star
   separation
  is still to small (~1 mas) to be directly resolved, but the high spatial resolution
  of NACO will reduce source confusion with unrelated sources in these crowded Bulge
   fields.
  
  The constraints from this two epochs together with our microlensing model based
      
  on our light curve data from our telescope network PLANET obtained in P79 will
  allow to significantly reduced the uncertainties in the mass of the planet candidate
  and its host and their physical separation.
  
  Since the targets are faint we PREFER STRONGLY the use of the LASER GUIDE STAR and
  the science OBs for this setup are marked with -LGS- in the OB name.
  
  Targets are observable for the whole period 81.
  Good seeing and photometric conditions are crucial.
  
  If for some reason however the Laser will not be operational for the whole period
   81,
  we prepared a backup setup using natural guide stars. The OBs are marked with -NGS-
   in their names.
  
  Further note that target MOA-197 is in nonstandard FNS-HS readout mode and we supplied
  a separate photometric calibrator for this target. All other targets (MOA-192 and
   O-349) 
  are in standard DCR-HD readout mode, supported by the calibration plan.

Waiver Requests

• Waiver request 381.C-0425A.01/02.WAV granted
  
  mail from 8.Feb.08:
  
  
  Dear Daniel, Dr. Cassan,
  
  Your waiver request to submit OBs of durations 1.5-2h was granted
  under the usual restriction that an OB will not be aborted or
  repeated if conditions degrade below constraints after the first
  hour.
  In that respect, it is important to optimize the OB duration in
  such a way that the program does not suffer too much, even if
  a part of an OB is executed with e.g. the seeing higher than
  specified.
  
  I'm looking forward to receiving your Phase 2 material,
  with best regards,
  Sabine

Critical Observing Condition Constraints

• We require a photometric night and good seeing (< 0.8" in VIS) to 
  resolve the target as good as possible from contaminating neighbouring 
  stars.

Time-Critical Aspects

• none, targets observable over complete period 81

Special Execution Requirements

• It is desirable to take the photometric standard close in time.
  NOTE that for OB MOA-197-XXX we suplied our own standard OB CAL_MOA-197 since
  this OB is in FNS-HS detector mode which is not supported in the standard calibration
   plan.
  The other two targets (MOA-192-XXX and O-349-XXX) are in standard DCR-HD readout
   mode.

Special Calibration Information

• For target MOA-197-XXX we supply our own photometric standard OB CAL_MOA-197
  since the non standard readout FNS-HS  is used for this target.
  The calibrator is cataloged in Persson as  S279-F-9172 (also in NACO OT queue for
   standards) and
  is about 12.5 in J, 12.1 (H) and 12.0 in K and of spec.type GOV.
    
  The closer in time the photometric standards are taken (ideally right before or
   after the
  science), the better  for the accuracy of the photometric calibration.
  
  The other two targets (O-349 and MOA-192) are in in standard DCR-HD readout mode.
