The Ring-Moon Systems Node currently archives three groups of data obtained by the HST. The three groups currently available are:
Observations of the Outer Planets from ACS, WFPC2, WFC3, and STIS.
Small Satellite Astrometry data,
Saturn 1995 Ring Plane Crossing data.
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 STScI 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 Ring-Moon Systems Node has developed a series of PDS compliant “data sets” of all HST observations of the Outer Planets using ACS, WFPC2, WFC3, STIS obtained since the initial Hubble repair mission. We make periodic updates at roughly six month intervals for the active supported instruments.
Although these “data sets” are PDS compliant, since their primary function is to support OPUS and since STScI periodically improves their calibration pipeline, our “data sets” have not undergone a PDS peer review, and do not contain the final calibrated versions of the data files.
We have placed all of these “data sets” on-line for browsing and direct download, but please note the caveats above.
The “data sets”, have been sorted into three volume set collections - one for each instrument. Within an instrument’s volume set collection, each “data set” corresponds to a single HST proposal.
Each “data set” contains detailed indices, TIFF and JPEG ‘browse’ versions of each image accompanied by a simple text file containing all FITS header information from the original image, and a PDS label file which includes specific instructions for obtaining the calibrated version of the image from STScI.
As of April 15, 2017 the ACS, WFPC2, and WFC3 “data sets”, and their most recent updates, have been incorportated into OPUS. We anticipate completing the inclusion of the STIS “data set” shortly.
The on-line directories are organized by instrument and proposal number. Directory names are in the form HST#x_xxxx, where # is replaced by a single letter that indicates which instrument obtained the data. We use the same letter identifiers for the instruments as STScI, “I” = WFC3; “J” = ACS; “U” = “WFPC2”, “O” = STIS. These are available for directory tree browsing, or for downloading as separate tar.gz files for each “data set”.
The Ring-Moon Systems 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.
The Ring-Moon Systems 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.
The Ring-Moon Systems 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.
