Abstract This proposal will perform FOC observations through filter F486N in the F/96 mode, to monitor focus stability of the HST OTA FOCAL Plane. Two targets in the CVZ will be observed alternately every 28 days for a total of six times. The visibility of the chosen targets in the CVZ differs by 28 days. The resource estimate for this estimate is 4.9 hrs. This number is obtained by dividing the RPS resource estimate by 3, since the targets are in the CVZ. ------------------------------------------------------------------------------------ ------------------------------------------------------------------------------------ 9.

Jedrzejewski ESA/FOC USA X ------------------------------------------------------------------------------------ 3. Description of proposed observations. A set of 4 images will be taken using the FOC F/96 with filter F486N. This test is to be performed a total of six times with 28 day spacings. Two targets have been specified in the CVZ the visibility period of which differs by 28 days. This means that for each execution of the test only one star will be observed. At any given time it does not matter which of these two targets is observed as long as it is the one currently in the CVZ. Consequently, it does not matter which of the two targets is observed first. ------------------------------------------------------------------------------------ 4. Justification of need for HST observations. The observations will provide data useful in assessing the HST OTA Focal plane desorption. ------------------------------------------------------------------------------------ 11.
