Voyager 2 MAG data in NLS coordinates near Neptune. The data are averaged to 12 second resolution and cover the time period 1989-08-24T18:00:00 to 1989-08-26T08:19:48. Also included in the DATA/MAG/NLS/ASCII directory is INTERNAL.TAB, a file containing the magnetic field values obtained at Neptune that were used in obtaining Connerney's spherical harmonic model of Neptune's internal field. The data are stored as 3 binary tables (*.DAT). Each data file has a PDS label file (.LBL) which describes some of the physical properties of the data. There is a single format file (.FMT) which describes the columns of the data files. /-------------------------\ | D A T A | \-------------------------/ Data Files (.DAT extension) ============================================================================== Name Records Cols Len Start Stop ------------------------------------------------------------------------------ T890824 1762 6 48 1989-08-24T18:00:00.557 1989-08-24T23:59:48.530 T890825 7034 6 48 1989-08-25T00:00:00.530 1989-08-25T23:59:48.418 T890826 2495 6 48 1989-08-26T00:00:00.418 1989-08-26T08:19:48.379 Columns ===================================================== name type description ----------------------------------------------------- ctime float_8 secs since 1966-01-01T00:00:00 pdstime char_24 time in PDS standard format Br float_4 radial Mag component Btheta float_4 theta Mag component Bphi float_4 phi Mag component Bmag float_4 magnetic field magnitude Catalog data which includes instrument, dataset, and data parameter descriptions are located at: /DATA/MAG/INST.CAT /DATA/MAG/NLS/12S/DATASET.CAT /DATA/MAG/PARM.CAT ============================================================================== MAX/MIN Statistics for: T890824 ------------------------------------------------------------------------------ :::::::::::::: T890824.stats :::::::::::::: /=====================================================================\ | D A T A F L O W S T A T I S T I C S | \=====================================================================/ Number of columns in data flow: 6 --------- Aggregate Statistics ---------- Total number of records: 1762 /======================================================================\ | COLUMN | MINIMUM | MAXIMUM | AVERAGE | #
