... The very first step after correcting bias, dark, and overscan is to find the edges of the slitlets. This is done by the command LOCATE/MOS . This command takes the central trace of a flat-field and detects the edges of the slitlet by simple threshold comparison. ... The offsets in dispersion direction between the slitlets will be read from the header of the flat-field frame for FORS data and stored in :xoffset . ... The actual flat-correction is then performed with COMPUTE/IMAGE . ...

. 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.
