Hourly Averaged Plasma Parameters

NSSDCA ID: PSFP-00084

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

Time span: 1971-07-31 to 1972-06-30

Description

This experimenter-supplied tape contains hourly averaged plasma parameters as observed on the moon at the Apollo 15 ALSEP site. The tape was written in BCD on a UNIVAC 1108 computer. Each set of averages is in 2 logical records, with 2 logical records per physical record. Four sets of hourly averaged parameters are computed, using as input data -- (1) all fine-time scale parameters (FTSP), (2) all FTSP computed from spectra with small rms error on curve fitting and thermal speeds less than one-half the bulk velocity, (3) all FTSP computed from spectra that satisfy the requirements or criterion 2 as well as having only one flow angle can be directly measured, and (4) all FTSP computed from spectra that satisfy the requirements of criterion 2 as well as having both flow angles directly measureable. Contained in each of the 4 sets of averages are the proton density, alpha-to-proton ratio, bulk speed, angle of flow, number of spectra, and rms deviations of each average.

During the local lunar night there is no solar wind signal so there are data gaps of about 15 days each lunation.

These data have been read, reformatted, and put online as part of the Lunar Data Project (see links below).
