A measure of the intensity of a region of the sky, based on the temperature of a black body that would emit radiation of the observed intensity at the given observing frequency. Frequently computed in radio astronomy using the Rayleigh-Jeans approximation, in which case it is directly proportional to the intensity per unit area. For thermal emission mechanisms, it may correspond to a physical temperature in an emitting region. If the frequency channels are narrow enough, one can expand the u-v coverage considerably with immunity to bandwidth smearing . A program designed to render hypertext documents, possibly with multimedia extensions such as graphics, sound and video clips, and to provide a means of navigating from one hypertext node to another.
Browsers act in a client-server relationship with remote computers as servers.
An actual or a perceived programming error or program deficiency. The bug may be in the eye of the beholder since a user may fancy an application similar to, but differing from, the one for which the program is intended. When real, may be fixed by a kluge . An error condition reported when a process has attempted to access a restricted or non-existent part of a computer's memory. Synonymous with segmentation fault .
