Saturn Encounter (Digitized)

NSSDCA ID: PSSB-03661

Availability: Data Identified but not Received

Description

This collection consists of digitized, color transparencies of Pioneer 11 images obtained from the Imaging Photopolarimeter experiment (IPP) during the encounter with Saturn. These images, supplied by the experimenter, encompass days of year (DOY) 237-248, 1979. Most of the images are faint, or distorted, or have many lines of missing information. The best frames among these are F35A, showing atmospheric structure of Saturn, polar hood, and the rings well. F12B is good for the ring structures, showing the rings only. Good images among the negatives are F37 (blue), F33A, F33R (red), F19.5B+R, and F12B and R. The best images among the color are F37, F33, F19.5, and F12. (The connotation of letters F and G carried on the scheme of designating approach and recession to Saturn as to Jupiter previously.) The information block on the stereo pairs gives range, phase central point latitude, start and stop times of exposure sectors, filter used, and data processed. The best stereo pairs are F37, F32, F12 (for rings), F19.5, and F33. Accompanying the photos is a partial listing of the photos with a brief description of features visible and a complete listing which gives the following information: (1) frame number (image seq. No.), (2) midtime in DOY, h, min; (3) range in km; (4) pixel size in km, (5) phase angle in degrees; (6) latitude; (7) local central meridian (LCM) and (8) a "not displayed" code. The "not displayed" code is explained separately.

For this digitization effort the NSSDCA scanned the various size color transparencies in collection PSSB-00030 at a resolution of about 600 dots per inch and output each image as one TIFF file. The NSSDCA also combined the TIFF images into a multipage PDF file to facilitate browsing. Both formats are included in this collection.
