Apollo 15 Lunar Surface Experiments Package Solar Wind Spectrometer 
28-Second-Resolution and 1-Hour-Average ASCII Data Bundle

Overview
========
This PDS4 bundle (urn:nasa:pds:a15sws_solar_wind_28s_1hr) contains Apollo 15 Solar Wind 
Spectrometer data migrated from the PDS3 volumes 
A15A-L-SWS-3-SOLAR-WIND-28S-RES-V1.0 and A15A-L-SWS-4-SOLAR-WIND-1HR-AVG-V1.0. 
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 15 Solar Wind Spectrometer (SWS) 
from 31 July 1971 through 30 June 1972. This data set also contains tables of 
time ordered, hourly averaged plasma parameters, mainly of the solar wind, as 
observed on the Moon at the Apollo 15 ALSEP site by the Apollo 15 Solar Wind 
Spectrometer (SWS) from 31 July 1971 through 30 June 1972.

This bundle contains the following collections:

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

Every Apollo 15 Lunar Surface Experiments Package Solar Wind Spectrometer 28-s 
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. 

Every Apollo 15 Lunar Surface Experiments Package Solar Wind Spectrometer 
1-h-averaged 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 15 Lunar Surface Experiments Package Solar Wind Spectrometer 
28-s and 1-h-averaged data files are in ASCII tables. All these data files may be 
read using the PDS4 Viewer tool. 
 

Documentation
=============
       
Chapter 10 "The Solar-Wind Spectrometer Experiment" of the Apollo 15 
Preliminary Science Report in the document collection describes the instrument,
instrument deployment, and observations of the Apollo 15 Solar Wind Spectrometer
Experiment. This dataset is described in more detail in 
"dataset_description.txt" in the document collection.
