USC Ultraviolet Data Plots


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

Time span: 1973-04-30 to 1980-09-30


This data set, submitted by the principal investigator in hardcopy form, was microfilmed by NSSDC and is available from NSSDC in that format. It covers both Pioneers 10 and 11 on the same roll. The plots give time-averaged counting rate vs clock-angle for the two-channel photometer. The title contains the Pss Pass (pss pppp ddd mmm dd yyyy), where pss = 10 for Pioneer 10 and pss = 11 for Pioneer 11, pppp = pass number or number of days since launch, ddd = day of year, mmm = month, dd = date, and yyyy = year. The Y axis represents the average count rate in counts per second, while the X axis gives the clock-angle in degrees. At the bottom of the plot are listed the following chan: H- hydrogen or lambda L, He- helium or lambda S, the channel of the instrument; interval times: time period for which the average is taken, given in hours, minutes, and seconds, as follows Min, Avg, Max = values for corresponding count rate given in counts per second; Min, Clock, Max = clock-angle where (minimum/maximum) count rate occurs; and # OBS = number of observations made by the instrument.
