Instrument Science Report NICMOS 2003-004 Measuring the Cold Mask Offset E. Roye, J. Krist, A.B. Schultz, T. Wiklind April 23, 2003 ABSTRACT An unexpected increase in measured thermal background during the Cycle 11 early calibration program caused speculation that the cold mask position could have shifted since Cycle 7. ... It was concluded that the cold mask position was not the cause of increased thermal background observed during the Cycle 11 early calibration program. ...

... My project was concerned closely with research, which in general went well. However it was difficult to find specific information relating to fossil fuel use and emission in the UK, though easy for the USA. This meant, at times, it was assumed that fossil fuel consumption in the USA and UK were roughly the same. It was also difficult to find on the Internet information about specific cities (e.g. Armagh), but by contacting a lighting engineer this information was obtained. ...

... These sources are much more likely to be gravitationally lensed by intervening galaxies as compared with sources discovered in surveys in other wavebands. ... The effect of lensing by clusters is then discussed briefly. This is expected to increase the source confusion noise in a Planck survey in the directions of clusters, and could provide information about galaxies with flux densities that are too faint to be detected directly by Planck . ... 2 The properties of galaxy--galaxy lensing . ...

... 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. ...
