NEAR Infrared Spectrometer (NIS) Level 2 Data Archive (PDS)

NSSDCA ID: PSPG-00722

Availability: At NSSDC, Ready for Offline Distribution (or Staging if Digital)

Time span: 1996-04-17 to 2000-05-13

Description

This data set contains calibrated data from the NEAR Near Infrared Spectrograph, as well as the documentation, procedures and data files required to replicate that calibration. The data set contains five volumes. NNEROS_2001 and NNEROS_2002 contain the NEAR infrared spectrometer (NIS) data in 2-byte binary format stored in a FITS file called the nixel (NIS pixel) database. They cover the CRUISE 1, CRUISE 2, EARTH SWINGBY, CRUISE 3, EROS FLYBY, CRUISE 4, and EROS ORBITAL phases. The data are calibrated, provided in scientific units, and formatted into FITS file format containing observational and engineering parameters as well as the 32-channel data and derived noise values for both the Ge and InGaAs detectors. Calibration files and algorithms are available: refer to the CALIB/ and DOCUMENT/ directories on this volume. The NIS database maintains large amounts of information along with each spectrum including instrument housekeeping, observational geometry, and footprint location on the target.

The NNEROS_2003 volume contains a new, PDS-generated version of the original NIS (Nixel) database found on volume NNEROS_2001. The original MET_HI_WORD and MET_LO_WORD columns were replaced with the calculated MET, 2) an offset was added to the raw data numbers for RAW_GE_DATA and RAW_INGASS_DATA so that all values would be positive, and 3) the original FITS header was modified to include a FITS-compliant binary table extension. The NNEROS_2004 volume contains the spectra on volume NNEROS_2003 grouped by UTC (observation) date. One FITS binary table was created for each UTC date. The NNEROS_2005 volume contains spectra grouped by NIS mission subphase. One FITS binary table was created for each subphase.

The data for this data set are stored on DVD volume NNCOLL_3001
