Abstract In this test we will obtain spectra of standard stars with relatively smooth continua, on a regular basis, to track the time-dependence of flat-field structure of the FOS Red detector in the UV. Spectra will be obtained in both the 4.3 aperture and the slit, since the flat- field structure is dependent on aperture size. ------------------------------------------------------------------------------------ ------------------------------------------------------------------------------------ 9.

GENERAL FORM Proposal 4123c PI: George Hartig Proposal Title: FOS SPECTRAL FLAT FIELDS MONITOR, REVISED ------------------------------------------------------------------------------------ 1. Proposers: Proposers Institution Country ESA ------------------------------------------------------------------------------------ Anne Kinney STSCI USA George Hartig STSCI USA Tony Keyes STSCI USA ------------------------------------------------------------------------------------ 3. Description of proposed observations. In this test we will obtain spectra of standard stars with relatively smooth continua, on a regular basis, to track the time-dependence of flat-field structure of the FOS Red detector in the UV. Spectra will be obtained in both the 4.3 aperture and the slit, since the flat- field structure is dependent on aperture size. ------------------------------------------------------------------------------------ 6. Description of special calibration exposures. This test is not stray light sensitive. ------------------------------------------------------------------------------------ 7. Data reduction and analysis plans. Data reduction will be performed at the STScI, and the analysis will be performed using STScI computer facilities. This is a calibration, so the resulting data will need to be added to CDBS for use in the PODPS pipeline. ------------------------------------------------------------------------------------ 11.
