Pioneer 11 Starlight/Zodiacal Light Experiment Data


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

Time span: 1974-05-28 to 1974-09-24


This collection contains reduced data of photopolarimetric measurements of the brightness of the sky. A user's guide explains the data parameters and format. The first file consists of a directory containing two records of tape identification information. There are a variable number of data files, each beginning with a header record containing day of year, input tape number, section number (each day's observations of the sky may be broken into as many as eight sections delineated by look angle), start and stop times of observations, ephemeris information, number of stars used to get pointing correction, standard deviation, number of look angles, and look angles included in the section. The data records contain right ascension and declination of center of field of view, elongation angle of sun, blue and red brightness in Experimenter Data Records (EDR) units, declination and right ascension of star, dwell time, and vignetting correction.

These data are available on-line at:
