General Description

• These observations are to resolve the disk around HD115892.  The disk
   is predicted to lie at 0."33.  As the spatial scale is small, we require a small,
   well constrained PSF.  Thus we have requested standard observations immediately
   before and after the star in both filters and excellent seeing conditions. The order
   of execution should therefore be HD110458 (standard), HD115892 (science target),
   HD110458 (standard) in both filters.  The standard star HD110458 is a K0III star,
   visual magnitude 4.667, flux in SiC filter 3.823 Jy, flux in Qa filter 1.554 Jy.
   
  Finding charts attached are 2MASS K band images.  For both the standard and science
   target the required object will be the brightest source in the field of view.

Waiver Requests

• No Waiver Request was submitted

Critical Observing Condition Constraints

• We require excellent seeing conditions as we are trying to resolve a disk
   source close to the resolution limit.

Time-Critical Aspects

• No time critical aspects

Special Execution Requirements

• We require three OBs to be executed consequetively (for each filter SiC
   and Qa).  The order of execution should be standard OB, science OB and standard
   OB. The standard target is HD110458.  The OB's are labelled HD115892_stdN-X (or
   Q) in the case of the standard star (where X is 1 or 2), and HD115892_sciN (or Q)
   for the science target.

Special Calibration Information

• Our standard star will be used for both photometric calibration and PSF
   determination.  As we require a good knowledge of the PSF we require two observations
   of the standard star to be taken for each associated science observation (one immediately
   before the science observation and one immediately after).
