END_OBJECT = TEXT END DATA Directory Contents ======== Overview ======== The Magnetometer (MAG) raw data on this disk reside in the directory DATA/MAG. These data were acquired by the Magnetometer instrument aboard the Near Earth Asteroid Rendezvous (NEAR) spacecraft. The time period of the data is listed in the file MAGDATASET.CAT, which can be found in the CATALOG directory on this disk. Each data file is a table of raw telemetry data in FITS format. For further information about the data, please consult the file CATALOG/MAGDATASET.CAT referenced above. ======================= File Naming Conventions ======================= The file naming convention for the data files is illustrated by the following example. MAG97220.FIT is interpreted as: MAG = Magnetometer data 97 = year 1997 220 = day of year 220 (where Jan. 1 = day of year 001) FIT = FITS format MAG97220.LBL is the name of the PDS label file which describes the data file MAG97220.FIT. Such label files provide descriptive information in a format which is both human-readable and machine-readable. ========= Documents ========= This disk contains documentation files which describe the data on the disk, the instruments from which the data came, and the NEAR spacecraft and mission. These files are found in the CATALOG and DOCUMENT directories, and are described in the files CATALOG/CATINFO.TXT and DOCUMENT/DOCINFO.TXT.
