ACS/CAL 9707

Elevated ACS CCD temperature study

To gain an understanding of the effects of detector temperature on hot 
pixel dark rates and CTE behaviour, measurements will be taken with 
the TEC set points at -71.5C and -66.7C. Bias and dark frames plus CTE 
images will be recorded at the normal operating temperature, -77C, and 
at the two higher settings

ACS/WFC 9575

Default {Archival} Pure Parallel Program.

The Advanced Camera for Surveys (WFC) was used to test ACS pure 
parallels in POMS.

ACS/WFPC2 9481

Pure Parallel Near-UV Observations with WFPC2 within High-Latitude ACS 
Survey Fields

In anticipation of the allocation of ACS high-latitude imaging 
survey{s}, we request a modification of the default pure parallel 
program for those WFPC2 parallels that fall within the ACS survey 
field. Rather than duplicate the red bands which will be done much 
better with ACS, we propose to observe in the near-ultraviolet F300W 
filter. These data will enable study of the rest-frame ultraviolet 
morphology of galaxies at 0 * Origin: SpaceBase[tm] Vancouver Canada [3 Lines] 604-473-9357 (1:153/719)
