ADC Data on CD-ROMs & Other Media
The ADC's astronomical catalogs and journal data tables are not only available via the Internet. Many of the most popular catalogs are available on the ADC's CD-ROMs. This can be a very convenient and cost-effective way to request ADC data, particularly for the larger catalogs. In addition, users may ask for selected data sets to be sent to them on one of several other computer media (e.g., CD-Recordable, 8mm tape, diskette).
ADC catalogs can be obtained off-line on CD-Recordable, magnetic tape and floppy diskette for a fee . Ordering information may be obtained from the NSSDC Coordinated Request and User Support Office.
Requests for ADC CD-ROMs may be placed by contacting theNSSDC Coordinated
Request and User Support Office or
by CD-ROM order form.

This information is compiled and is available via FTP from adc.astro.umd.edu in the /pub/adc/errors/ directory. Requesters are advised to check this information to ensure that they are using the best available data.
