Use OPUS to search for specific Cassini UVIS data products using a wide range of criteria including enhanced geometric metadata produced at the Rings node. The enhanced geometric metadata includes information appropriate to planet and satelllite searches as well as enhanced ring geometry.
The Access UVIS Data tab, associates volumes with data sets, and for each volume gives the time interval covered by the volume and provides a link to the volume.
NOTE: We provide links to individual volumes. Each volume contains data from several different UVIS data sets.
The PDS Atmospheres Node provides links to individual data sets.
For more information on UVIS data sets and data volumes, see the About UVIS Data tab.
You can use the DATA_SET_ID field to narrow your search. It is in the form CO-[T]-UVIS-2-[DESC]-V1.0, where:
CO is the Cassini Orbiter
[T] is a PDS target ID:
* **X** for cruise data
* **J** for data taken at Jupiter
* **S** for data taken during the Saturn phase of the mission.
UVIS is the instrument name
2 indicates the CODMAC data level (raw)
[DESC] is one of the following abbreviated descriptions of the data set:
* **CALIB** \- Calibration data
* **CUBE** \- A multi-band image (in PDS QUBE format)
* **SPEC** \- A spectrum
* **SSB** \- A time series of photometric (occultation) data
* **WAV** \- An image at one wavelength
The volume ID takes the form: COUVIS_XXXX, where:
COUVIS is the PDS abbreviation for Cassini Orbiter, Ultraviolet Imaging Spectrograph
XXXX is the sequential volume number, begining with 0001
The Access UVIS Data tab, associates volumes with data sets, and for each volume gives the time interval covered by the volume and provides a link to the volume.
Each volume has an INDEX subdirectory containing several files including:
Users are strongly encouraged to read an INDXINFO.TXT before working with the INDEX files.
INDEX.TAB: an ASCII table file with one row for each data file on the volume. For Cassini UVIS, each index table approximately 45 columns. This example is from disk COUVIS_0002.
INDEX.LBL: the detached PDS label file for the INDEX.TAB file. This is a text file giving names and definitions of all the columns in the index.
