Apollo 12 Lunar Surface Experiments Package Solar Wind Spectrometer 
28-Second-Resolution and 1-Hour-Average ASCII Data Bundle

Overview
========
This PDS4 bundle (urn:nasa:pds:a12sws_solar_wind_28s_1hr) contains Apollo 12 Solar Wind 
Spectrometer data migrated from the PDS3 volumes 
A12A-L-SWS-3-SOLAR-WIND-28S-RES-V1.0 and A12A-L-SWS-4-SOLAR-WIND-1HR-AVG-V1.0. 
This dataset contains daily tables of time ordered, 28-second-resolution 
plasma parameters, mainly of the solar wind, as observed on the Moon at 
the Apollo 12 ALSEP site by the Apollo 12 Solar Wind Spectrometer (SWS) 
from 19 November 1969 through 25 March 1976. This is the highest resolution 
data set available from the SWS instrument. It also contains tables of time 
ordered, hourly-averaged plasma parameters, mainly of the solar wind, as 
observed on the Moon at the Apollo 12 ALSEP site by the Apollo 12 Solar Wind 
Spectrometer from 19 November 1969 through 25 March 1976.

This bundle contains the following collections:

Data Products and PDS Labels
============================

Every Apollo 12 Lunar Surface Experiments Package Solar Wind Spectrometer 
28-Second-Resolution and 1-Hour-Average data product is accompanied by a 
PDS label in a file with the same name as the data file, but with the 
extension ".xml", as PDS labels are written in XML (Extended Markup Language). 
The labels may be viewed in a text editor or web browser, preferably one 
that applies special formatting to XML files to make them more readable. 
The labels may also be read by software that can interpret XML. 

Apollo 12 Lunar Surface Experiments Package Solar Wind Spectrometer 28-s and 
1-hr-average data files are in ASCII tables. All these data files may be 
read using the PDS4 Viewer tool.  

Documentation
=============
       
Chapter 5 "The Solar-Wind Spectrometer Experiment" of the Apollo 12 
Preliminary Science Report in the document collection describes the instrument,
instrument deployment, and observations of the Apollo 12 Solar Wind Spectrometer
Experiment. This dataset is described in more detail in 
"dataset_description.txt" in the document collection.
