HST Data at the PDS Rings Node
The Rings Node currently archives three collections of data obtained by the HST. We intend to add a fourth collection, data obtained during the 2007/2008 Uranian Ring Plane Crossing season, as that data becomes available. The three collections currently available and being expanded are:
Observations of the Outer Planets
HST provides some of our finest Earth-based data on the outer planets. Literally hundreds of planetary programs have been carried out using HST. All HST products can be found in the Multimission Archive at STScI, MAST, and can be calibrated on-the-fly prior to retrieval using the most current calibration files and algorithims. .
Although the files are reliably archived, the search interface is not well adapted to planetary queries. In order to incorporate this rich data collection into the search data base for our planetary science specific search tool, OPUS, the Rings Node is developing a series of PDS compliant data sets of all HST observations using ACS, NICMOS, or WFPC2 of the Outer Planets made since the initial Hubble repair mission.
These data sets, each corresponding to a single HST proposal, will contain TIFF and JPEG 'browse' versions of all images, plus text files containing all FITS label information, and detailed indices. Because STScI periodically improves calibration, we do not include the final calibrated data files. Instead we provide links to the HST archive where the calibrated files can be obtained. Our data sets for WFP2 are now on- line for browsing and direct download and will be incorportated into OPUS shortly. At that time, users will be able to tailor a search of our HST data by target and instrument, and will be able to apply a wide variety of observational and geometric constraints to the search.
The initial collection will encompass observations made through mid-2007. Each data set corresponds to a single HST proposal. The on-line directories are organized by instrument and proposal number. Directory names are in the form HST#x_xxxx, where # will be replaced by a single letter that indicates which instrument obtained the data. We use the same letter identifiers for the instruments as STScI, "J" = ACS; "N" = NICMOS; "U" = "WFPC2".
As these volumes become available, users may browse the directory trees and download tar.gz bundles for each data set.
Small Satellite Astrometry
The Rings Node currently has two volumes of astrometric HST data for the small satellites of Saturn. For more information about and links to the data, see Satellite Astrometry.
Saturn Ring Plane Crossing (SRPX)
The Rings Node currently has nine volumes of SRPX data of which the first five volumes were obtained by the HST. For more information on the SRPX seasons, the information about and links to the associated data and links to relevant web sites, see Saturn RPX.
Uranus Ring Plane Crossing (URPX)
The Rings Node currently has no data from the URPX observing campaign. We do anticipate receiving and archiving such data as it becomes available. For more information on the URPX seasons and links to relevant web sites, see Uranian RPX.
