DATA_SET_DESC = " Data Set Overview ================= This data set contains daily tables of time ordered, 28-second-resolution plasma parameters, mainly of the solar wind, as observed on the Moon at the Apollo 15 ALSEP site by the Apollo 12 Solar Wind Spectrometer (SWS) from 31 July 1971 through 30 June 1972, when the instrument failed. This is the highest resolution data set available from the SWS instrument. Data ==== The 28-second SWS data tables are in fixed-width ASCII format. There is one table for each daily set of SWS measurements. During the local lunar night there was no solar wind signal so there are data gaps of about 15 days each lunation. Each daily table contains a sequence of plasma measurements made every 28.1 seconds. Each record in a table provides the time of a measurement, proton density, alpha-to-proton ratio, proton bulk speed, and angle of flow. Each record identifies the Faraday cup on the side of the instrument (one of six) that measured the most charge. The measured charge of this cup, the adjacent side cups, and the vertical (top) cup are included in each record as well as the most probable thermal speed, and various housekeeping and fit parameters relating to the reliability of the calculated plasma parameters. Note that a value of 99.0 in Column 14, the Percentage Error in Fitting Program, indicates the fit was bad and thus all computed plasma parameters in that row are invalid. These data tables were converted from the CDF format which was created from the original binary data set PSFP-00113 by the NSSDC as part of the Lunar Data Restoration project. The original tapes were written in BCD format on a UNIVAC 1108 computer. See Clay, et al. (1972) [CLAYETAL1972], Goldstein, et al. (1973) [GOLDSTEINETAL1973] and Clay, et al. (1975) [CLAYETAL1975] for more information about the SWS plasma data from Apollo 15. The NSSDC restored all data that were available in the original binary data set. There are gaps within the tables in this PDS data set because there were no data available at the NSSDC for those periods of time. This data set description was provided by the NSSDC. " CONFIDENCE_LEVEL_NOTE = " Confidence Level Overview ========================= These data tables are restorations of the original binary data recorded by the SWS experiment and were reviewed internally at the NSSDC for accuracy and completeness. There are gaps within the tables in this PDS data set because there were no data available at the NSSDC for those periods of time. Review ====== This data set was peer-reviewed in December 2007 and was accepted for the PDS archive pending the resolution of liens (completed in August 2008).
