This data set contains raw telemetry data, provided in engineering units, from the NEAR infrared spectrometer (NIS). In addition to the raw spectrometer data, a calibration file and algorithm are available. The data are in the form of FITS files with atached FITS headers and detached PDS labels. Files contain all data for one day. The files are subdivided into one file per NIS acquisition sequence. Each file has a 11520 byte ASCII header followed by 16-bit binary image data. The binary image data consists of 108 columns of spectral and ancillary housekeeping information and a variable number of rows (one row per spectrum) depending on the specific sequence.
The data are divided into volumes which contain cruise, Eros fly-by, Eros orbit, and Earth fly-by data. The volumes containing each file, the PDS ID, and the data range covered (in the form YYYYDDD) are given below:
NNCRU1_0001 NEAR-A-NIS-2-EDR-CRUISE1-V1.0 1996051 - 1997175
NNCRU2_0001 NEAR-A-NIS-2-EDR-CRUISE2-V1.0 1997179 - 1998022
