OM Visual Grism Calibration using G158-100

CALThe primary goals of the observation of the G158100 is thespectrophotometric calibration of the grism and the calibration of the grismPSF. Secondary calibration goals are the verification of the wavelength scaleusing spectral features in the spectrum of G158100. Furthermore it is intendedto measurement the instrument PSF of the nondispersive filter elements byplacing a fast mode window ontarget. The target count rate and the PSF shape isstudied under count to framerate ratio. The study also includes an OM defaultconfiguration. Field stars are used to verify the astrometric solution. Theestimated OM overhead time is 12.6/2.9/9.9 ksec for the unsplit observation/1stpart/2nd part of the initial observation and 10.9ksec for folluw up observation. truncated!, Please see actual data for full text [truncated!, Please see actual data for full text]
