New Horizons Solar Wind Around Pluto Calibration Files - Overview
=================================================================

Content
-------
This collection contains ancillary files used in the calibration of data 
from the Solar Wind Around Pluto (SWAP) instrument for all phases of 
the New Horizons primary and extended missions. The collection consists of  
files such as background, response functions, field of view mask, and
energy bins.

Some products appear in multiple versions as a result of changes and/or
improvements over the course of the missions. For these product lines, the 
calibrated data will reference the specific version of the product in this 
collection that was used in its production. So while some of these files 
were "superseded" in terms of what was used in later versions of the pipeline, 
they are not "superseded" in an archival sense because they are applicable to 
the data produced using them.

The files were presumably collected by the SWAP team.  In the PDS3 data, the 
Producer Institution Name was listed as Southwest Research Institute.  The 
PDS4 migration was performed by SBN personnel, who are credited as editor of 
this collection.

PDS3 to PDS4 Migration Notes
----------------------------
The PDS3 versions of many of these calibration files were duplicated in every 
SWAP PDS3 dataset archived. For the migrated PDS4 archive, only a single 
instance of each version of each file was retained. 

The PDS3 labels, which contained minimal metadata beyond data structure, were 
not retained in the migrated PDS4 archive but are accessible in archival copies
of the PDS3 datasets retained in the NSSDCA deep archive.
