Principal Investigator Institution Country Telephone Perry Greenfield SPACE TELESCOPE SCIENCE INST USA ------------------------------------------------------------------------------------ 7. Abstract The relative pixel to pixel response of the FOC over the entire field of view will be measured using the onboard LEDs. Format dependent sensitivity effects will also be checked as well as pattern noise at low count rates. Observations should be performed in parallel mode. ------------------------------------------------------------------------------------ ------------------------------------------------------------------------------------ 9.

Description of proposed observations. The LED exposures will allow us to map the relative DQE over the face of the individual detectors at the pixel level. The data will be used to update "master" DQE files in CDBS for use by the RSDP pipeline processing. A format-dependent variation in sensitivity has been noticed. A series of exposures taken at the same LED intensity setting but in different formats will be used to measure the effect. Pattern noise appears to disappear at low count rates. A series of exposures is included to determine the count rate threshold. Many of the exposures require a nonstandard configuration, i.e., the use of filters during an LED exposure. ------------------------------------------------------------------------------------ 5.
