Observers may ftp their data via Internet, or they may purchase either an exabyte or DAT tape from the Observatory. DAT and exabyte tapes are $10.00 each; observers will be invoiced for tapes. The observer may elect to take the tape with him, or he may have the tape shipped to him. In either case, a Data Tape Request Form MUST be completed at the 12 Meter, before the observer leaves.
