1) Apollo 12 Solar Wind Measurements at the Lunar Surface 1-HR Data maxmize
Resource ID:spase://VSPO/NumericalData/Apollo12-LM/SWS/PT1HR
Start:1969-11-19 19:30:00 Observatory:Apollo 12 Lunar Module/ALSEP Cadence:60 minutes
Stop:1976-03-25 08:30:00 Instrument:Solar Wind Spectrometer Resource:NumericalData
This data set contains hourly averaged plasma parameters from the Apollo 12 Solar Wind Spectrometer. 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 of criterion 2 as well as having only one flow angle that 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.

2) Apollo 12 Solar Wind Measurements at the Lunar Surface 28-s Data maxmize
Resource ID:spase://VSPO/NumericalData/Apollo12-LM/SWS/PT28S
Start:1969-11-19 18:42:13 Observatory:Apollo 12 Lunar Module/ALSEP Cadence:28 seconds
Stop:1976-03-25 08:35:57 Instrument:Solar Wind Spectrometer Resource:NumericalData
This data set contains the highest time resolution plasma data available (28 sec per spectrum) from the solar wind experiment onboard Apollo 12. Contained in each record are: time, proton density, alpha-to-proton ratio, bulk speed, angle of flow, most probable thermal speed, and various housekeeping and fit parameters relating to the reliability of the calculated plasma parameters. During the local lunar night there is no solar wind signal so there are data gaps of about 15 days each lunation.
