Data Set Overview
=================
NEAR EDR volume sets contain a single data set, from one instrument
and one mission phase (defined in the phase table in /AAREADME.TXT).
The data set directory structure is shown below. The first volume of
the set is the only volume which contains CATALOG, DOCUMENT
and other non-data subdirectories. Subsequent volumes contain
only DATA and INDEX subdirectories in order to minimize duplication.
Volume 1 directory structure:
|-CATALOG--

|-DATA-----

| |-INSTRUMENT-|-CALPAPER---
|-DOCUMENT-|
| |-MISSION----|-OVERVIEW---
| |-TECHDIGEST-
|-GEOMETRY-

Volume 2-n directory structure
|-DATA-----

Directory Name Description
-------------- -------------
CATALOG Templates for the mission, instrument host,
instrument, and data set.
DATA Instrument FITS data files and data labels.
DOCUMENT Documentation of the instrument and mission are
provide as ASCII text and may also be available in
the original PostScript, PDF or MMS Word format.
Articles from the Johns Hopkins APL Technical Digest
are provided for an overview of the NEAR mission.
The instrument subdirectory contains documentation
describing the instrument and the in flight
calibration of instrument data.
GEOMETRY This directory contains only a GEOMINFO.TXT file.
A separate GEOMETRY volume contains all of the SPICE
kernels in text transfer format for the mission phase
and the supporting the supporting documentation.
INDEX INDEX TABLES for this CD and the volume set
describing times and key data file parameter values.
-------------------------------------------------------
Parameters
==========
The definitions for the image parameters and other keywords are
given in the file NLRDEFINITIONS.TXT contained in the
DOCUMENT/INSTRUMENT subdirectory.
Data
====
The data are in the form of FITS files with attached FITS headers
and detached PDS labels. Files contain all data for one day.
Ancillary Data
==============
GEOMETRY subdirectory is described above.
Media/Format
============
This data set is released as a CDROM set.
Processing History
==================
The processing history includes no background, noise, geometry or
other corrections.

Data Quality Flag
=================
Each data file label includes a quality flag string in the
DATA_QUALITY_ID keyword, extracted from the FITS keyword NEAR-008 of
the original data label. The fields of this keyword are defined
below. Data quality defects flag is raised when there is missing
data other fields informational and not quality related. The eight
characters of this field are described below.
Definition - Data Quality Index
c0 = Data Quality Flag (0=good,1=flagged for quality
defects)
c1 = Instrument number for FC, CTP and AIU (1 or 2)
c2 - c6 = Processing Flags not quality related
c7 = CCDS Source (0=VC0, 1=VC1, 2=VC2, 3=VC3)
Review
======
This data set underwent external peer review within PDS in June,
