This self-documenting database query program will search either for calibrators in the VLA Calibrator List or for sources from the observation archive list. The Calibrator List may be searched by source name, frequency, flux density, or area of sky. The archive list may be searched by source name, frequency, position, proposer or project number. VLASORS can be run on any MS-DOS PC with a hard disk. The archive of all observations with total integration times longer than one hour requires 4 Mbytes of hard disk storage. The file of all observations requires 8 Mbytes. VLASORS can be obtained by anonymous-ftp from the /pub/vlasors directory--get the read.me file first for detailed instructions.
You can also search the VLA Calibrator List from the World-Wide-Web by linking to http://www.nrao.edu/~gtaylor/calib.html.
