Saturn,Titan,and Delta Scorpii Encounter Data


Availability: At NSSDC, Ready for Offline Distribution (or Staging if Digital)

Time span: 1981-08-12 to 1981-08-25


These Saturn encounter data are contained on ASCII magnetic tape created on a VAX 11/780 computer. The data consist of atmospheric measurements for Saturn and Titan, and a stellar occultation of Saturn's ring system. The Saturn data are divided into three groups: (1) the "East-West Map", (2) the "North-South" scans, and (3) the "Belt" and "Zones" scans. The "East-West" map is a raster scan of the 0.11 deg field of view across Saturn's northern hemisphere at a phase angle of 10 deg. These were limb-to-terminator scans at 5 latitude bands. Group 2, the three "North-South" scans are along the central meridian. The high resolution limb-to-terminator scans in the "Equatorial Zone" and "North Equatorial Belt" at phase angles up to 68 deg are in the third group. The whole disk intensity and polarization observations of Titan cover phase angles from 3 to 154 deg. The stellar occultation data were obtained using the 2640-A filter, the 45-deg analyzer, the 1.0-deg circular aperature, a 0.0075-second integration period, and high-gain voltage. The data have been averaged into bins of 600 integrations. The star, Delta Scorpii, was observed continuously from its emersion from behind Saturn's disk through the shadowed D, C, B, A, and F rings.
