... This paper describes the main algorithms used by the Einstein Level One processing to create the exposure masks and the background maps for Einstein IPC images, and how these algorithms were recreated in the IRAF environment. Our goal was to recreate the algorithms used by the Level One Processing to create exposure masks and background maps for Einstein Image Proportional Counter (IPC) data (cf. sections 2.5 and 2.7 of Harnden et al. ...

... The FOC suffers from various types of background, the most important of which are thermal electrons, Cerenkov radiation from high energy particles, geocoronal emission lines, zodiacal light, and light scattered within HST from the bright Earth or Moon. ... From on-orbit measurements using the f /96 camera, the former background has been found to vary with solar zenith distance (ZD); see Sections 6.4, 6.5, and 7.0 of the FOC Instrument Handbook , version 7.0, for more details. ...

With the Phase I CGPS now complete at 21cm, we are in a position to examine the population of cold H I clouds over the entire range of the survey. Current methods of H I self-absorption (HISA) identification and analysis allow us to explore the properties and distribution of the portion of cold H I which appears as HISA shadows in the 21cm line data. Such studies are necessarily biased toward clouds with bright background emission. ...
