... 314 Astronomical Data Analysis Software and Systems XIII, eds. F. Ochsenbein, M. Allen, & D. Egret (San Francisco: ASP), 812 . ... Abstract: The calculation of flux upper limits in the source-free ("background") regions of photon-limited images is complicated by instrumental and statistical modeling and requires non-trivial computational effort. ... The principal component in this is the time taken to pre-process and handle the 30 GB of RASS data rather than the calculation of each upper limit. ...

... These are ``quirks'' rather than ``bugs''. Below is a list of quirks. When loading a file and ``Reset Intensity Upon File Load'' is disabled, the intensity range of the previous image will be used. ... When moving between two images (such as when blinking, or when loading a new image), the display system attempts to retain the old image parameters (i.e. zoom box). What is retained are the corners of the zoom box measured in image pixel co-ordinates, not world co-ordinates. ...

Instrument Science Report WFC3 2002-02 Expected WFC3-IR count rates from zodiacal background M. Stiavelli January 18, 2001 ABSTRACT This report captures the present estimates on the count rate from zodiacal background seen by the WFC3 instrument. The instrument as currently designed allows for background limited observations in the J band. ... The count rate from zodiacal background is estimated from a a simple model of the IRAS background as a function of the angles. ... Table 1. ...

The overall efficiency (including atmospheric transmission, reflectivity of the telescope mirrors and overall efficiency of the optics and of the detector) for broad-band imaging should be about 25% in H and K, and about 15% in J. The main noise source for both broad- and narrow-band imaging should be the photon noise associated to the background+source flux. ... Flat fielding (and possibly background subtraction) might increase the noise by a factor 2 ? ...

Total dose radiation effects in CMOS devices can be divided into two broad classes: charge trapping and interface state generation. ... When interface states are located in a depletion region, they act as sources of dark current. Increased dark current is expected to be the dominant radiation effect in active pixel sensors, leading to increased shot noise. ...
