... Moving the sample locations to achieve the desired warping will result in an irregularly sampled image plane. These irregularly spaced samples will then be brought back to regularly spaced positions, hence warping the image. ... The sampled impulse response, , is a function of the sample positions, . ... Allowing the sum to go outside the image boundaries ( or ) includes some ``anchor'' samples outside the image, which tends to stabilize the solution trajectory when is minimized. ...

... The Advanced Visual Systems (AVS) has been used to explore lines of sight through the complex geometry of the Green Bank Telescope (GBT). Perspective images computed by AVS from geometric descriptions of the components of the telescope have been used when selecting locations for the installation of laser rangefinders and when checking geometrical relationships along the optical path. ... The AVS ``camera'' could be commanded to look from any location in the scene toward any another location. ...

. Unix commands are executable binary files located in directories with the name bin (for binary). Many of the commands that you use are located in the directory /usr/bin . When you enter the name of a command the shell checks to see if it is a built-in command. If it is not, it looks for the the binary file that the command name refers to in each of the directories that are defined in the PATH environment variable . more ...

. In an effort to provide a centralized database for indexing locations and descriptions of Shuttle debris, the editors of Astronomy Net have generated a database and web page where reports can be logged. This may or may not prove useful for cataloging debris reports, but Astronomy Net is happy to dedicate computer resources to help out any way possible. We express our sympathy and prayers to the families and friends of the Columbia crew. If you have located Shuttle debris, report it here.
