Proprietary Rights on HST Data
In accordance with NASA policy, all science data from the Hubble Space
Telescope is archived with a one-year proprietary period
by default. This period may be extended or shortened at the request of the
principle investigator (PI) and on approval by the STScI Director's Office.
Calibration data (i.e., data obtained under calibration proposals), by default,
carries no proprietary period; neither does engineering data, calibration
files (derived from calibration observations), and observatory monitoring data.
In addition to the regular proprietary period, observations by General Observers (GOs) which are found to
be duplicates of concurrent observations by a
Guaranteed Time Observer (GTO) may be placed under
restriction. Data under restriction (or "embargoed") cannot be distributed
to the GO until the restriction expires (usually, when the GTO data goes public).
Policy for Submitting a Proprietary Rights Modification
Requests for proprietary rights modifications (extensions, reductions,
and/or restrictions) are handled by the archvie help desk https://stsci.service-now.com/mast or send mail to email@example.com. You must sign in with your MyST account to use the web portal.
The help desk staff will forward all requests to the
appropriate authorizing officials. All requests must go through an approval process
before being enacted.
