How do I obtain anonymous FTP access to the ADC archives?
The ADC now has over 880 astronomical catalogs and 1600 journal tables retrievable on-line via anonymous FTP. For direct FTP access, from Internet connect as follows: ftp adc.astro.umd.edu or 128.183.243.5 Log in as “anonymous”. Once connected, move to the pub/adc/archives subdirectory which is the root of the catalog and journal table archive directories. You will normally find a “key” file present at each level of the directory tree which contains an index of each subdirectory. Please note that all catalogs and journal tables except for the “ReadMe” files and other miscellaneous documentation files are stored in a UNIX compressed format. The “ReadMe” file, should be read first, it normally contains the catalog and journal table identification, a summary of the files, description of the data and format description. When copying the files via anonymous FTP be sure to use the binary option, and the decompression program “gunzip” on the copied files in order to obtain the original files.
