The Space Telescope Science Institute welcomes users to the HST data archive. Registration entitles you 
to a personal account on one of two workstations-your choice of VMS or Unix. Only registered users 
can retrieve data. Unregistered users can still access the HST catalog using the guest account.

To request an account, complete this form and mail it to the address at the bottom of this page: your 
account will be activated within two working days after it is received at STScI.
Users of the STDATA and STDATU accounts are expected to maintain their accounts in a secure manner. 
This includes choosing reasonable (non-simple) passwords, changing passwords often, and notifying 
archive@stsci.edu immediately if there is any evidence of break-in. Users should not share 
accounts. Note that there is a quota on the total amount of archive data that an individual can retrieve and 
this limit is based on the username. Archive accounts are being set up with limited access to Institute 
software and are not for general purpose computing. Use of these accounts will be monitored.
List root names of datasets below. (Use an additional sheet if necessary.)

You will receive all files associated with each dataset, unless you request specific files.
