Black and White Photopolarimeter Imagery


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

Time span: 1974-11-30 to 1974-12-04


This data set consists of B/W negatives of Pioneer 11 images obtained from the Imaging Photopolarimeter experiment (IPP). When the caption is at the bottom, north is up and the rising limb is on the left. The images are displayed at a constant scale of 0.8 mm/spacecraft roll (scan by IPP). There are two images (one red and one blue) for each frame number. The numbering system proceeds from high numbers and decreases until closest approach designated C, such that number 1 is at Jupiter periapsis. Numbers then increase on the outgoing trajectory and are designated D. For example, image A104R, for which film was exposed through a red filter, was obtained while the spacecraft was approaching Jupiter at a far distance from the planet. The numbers were assigned before image display, so there are some numbers for which good data were not obtained. The quality of the images ranges from poor to good.
