DATA_SET_TERSE_DESCRIPTION
DATA_SET_DESCRIPTION
Data Set Overview : This data set contains X-Ray Spectrometer (XRS) observations made during the third cruise phase of the NEAR mission. The individual observations are combined into a single file per day for each sensor.   Parameters : The data are presented as FITS binary tables (using the BINTAB extension) with detached PDS labels. The parameters listed in each table vary with observing sensor. The detailed descriptions of the various parameters included in the table are given in a separate documentation file, one for each sensor:  XRFDEFINITIONS.TXT XRSDEFINITIONS.TXT   Data : The data are in the form of FITS files with attached FITS headers and detached PDS labels. The data subdirectory has subdirectories for each instrument sensor. Files contain all data for one day.  Ancillary Data : Geometry data (pointing and attitude information) are provided for the entire NEAR mission as a separate data set.   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 observation includes a quality flag in the column named 'DQI'. This flag was 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, 2000.
