In the above example, the all of the ``IMAGE" options are on-line data products, so replying Y at any of these prompts will result in an error message.

Request prompts the user for an e-mail address. Near-line datasets are copied to our anonymous ftp area, ledas-ftp.star.le.ac.uk, and an acknowledgement is then sent via e-mail to the user. The files within each dataset are compressed then bundled together into a Unix tar file. To access the dataset, rp123456n00, for example and recover the files,
