OM Spectrophotometric Grism Calibration using GD 153

CALThe primary goals of the observation of the white dwarf GD 153 are thespectrophotometric calibration of the grism and the calibration of the grismPSF. The calibration is repeated for different field positions by offsetpointings. Secondary calibration goals are the verification of the wavelengthscale using spectral features in the spectrum of GD 153, the validation of thezero point of the UV filter and the Vfilter and a measurement of the PSF inthese filters. The estimated OM overhead time is 6.7/6.5 ksec foronaxis/offset pointings. truncated!, Please see actual data for full text [truncated!, Please see actual data for full text]
