HUBBLE SPACE TELESCOPE - Continuing to collect World Class Science DAILY REPORT # 4272 PERIOD COVERED: UT January 04, 2007 (DOY 004) OBSERVATIONS SCHEDULED ACS/WFC 10798 Dark Halos and Substructure from Arcs & Einstein Rings The surface brightness distribution of extended gravitationally lensed arcs and Einstein rings contains super-resolved information about the lensed object, and, more excitingly, about the smooth and clumpy mass distribution of the lens galaxies. The source and lens information can ...Continue Reading

HUBBLE SPACE TELESCOPE - Continuing to collect World Class Science DAILY REPORT # 4271 PERIOD COVERED: UT January 03, 2007 (DOY 003) OBSERVATIONS SCHEDULED ACS/HRC 11041 ACS CCDs daily monitor This program consists of a set of basic tests to monitor, the read noise, the development of hot pixels and test for any source of noise in ACS CCD detectors. The files, biases and dark will be used to create reference files for science calibration. This programme will be for the entire lifetime of ACS. For cycle 15 ...Continue Reading
