Estimated Total Execution Time (hours, including overheads)

General Description

• This is the continuation of our monitoring program to measure the astrometric
   motion of our target due to its unseen companion with high astrometric precision.
   We therefore need our OBs to be executed in pairs of calibration/science in time
   intervalls of approximately three weeks.
  To measure the astrometric motion we use a reference star in our FoV, 2MASSJ02190953-3646596.
   The target GJ1046 in the science OBs, GJ1046-8...10, is also used as the wavefront-star,
   R1, and is the brightest object in the FoV with V=11.61.
  Due to the big separation between target and reference star we cannot center the
   FoV onto the target. Instead we need another pointing, whose coordinates are clearly
   marked in the finding charts. To ensure, that with our choosen jitter-pattern both
   stars are always fully inside the FoV and to avoid crosstalk with appearing ghosts,
   it is very important to then center the reference star, which is in the lower right
   corner of the FoV, on the pixel (X=917, Y=65) of the S27 detector for all science
   OBs!
  For the same reasons we need the lower star, 2MASSJ0024303032-7204585, in the chart
   for the calibration OBs, CAL_47_Tuc-8...10, the southernmost object, to be centered
   on the pixel (X=917, Y=105) after the pointing. The pointing for the center of the
   detector is given in the finding charts, too. The wavefront star in the calibration
   field is the brightest, northernmost object in the FoV with V=11.82.

Waiver Requests

• We requested two waivers (381.C-5057A.01)  on 16. January, which were
   both approved on 18. January.
  The first request was concerning the distribution of OBs over P83 in calibration/science
   pairs. We asked for the consecutive execution of our calibration and science OBs,
   with the calibration OBs first.
  The request for exceeding the 1h limit for the single science OBs was approved,
   too.

Critical Observing Condition Constraints

• We hav no critical observing condition constraints.

Time-Critical Aspects

• Due to visibility of our target, the execution of the OBs is not possible
   befor end of July.
  The calibration OBs, named CAL_47_Tuc-8..103, need to be executed right before the
   corresponding science OBs, named GJ1046-8...10, due to visibility reasons.
  We aim to measure the astrometric motion of our target star due to its unseen companion.
   Therefore we need the three calibration/science OB pairs be executed in time intervalls
   of roughly three weeks.
