This directory contains Voyager 1 MAG 48 second averaged spacecraft magnetic field estimates. These data were recorded during the Voyager 1 Jupiter encounter, 2/26/79 - 3/24/79. The data are stored as 4 ASCII tables (.TAB), each covering about one week of data and named for the day on which the interval covered begins. File naming follows the convention Tyymmdd where yy = the last two digits of the year (79 for 1979), mm = month of year, and dd = day of month. Each data file has a PDS label file (.LBL) which describes properties of the data file. There is a single format file (MAGDATA.FMT) which describes the data files' columns. The file DATASET.TXT contains a more detailed description of data set contents. Additional information associated with these data is available in the following files: file contents /CATALOG/MAGINST.CAT MAG instrument description /CATALOG/PERSON.CAT personnel information /CATALOG/REF.CAT key reference description /DATA/MAG/INST.TXT MAG instrument information (copy of /CATALOG/MAGINST.CAT) /DOCUMENT/MAG/MAGINST.ASC ASCII and HTML versions of the MAG investigation and MAGINST.HTM description paper [BEHANNONETAL1977] /-------------------------\ | D A T A | \-------------------------/ Columns in all data files: ===================================================== name type description ----------------------------------------------------- time a24 time in format yyyy-mm-ddThh:mm:ss.sssZ m65536 i5 s/c clock mod 65536 mod60 i2 s/c clock mod60 mag_id i1 magnetometer ID Bx 1pe15.8 spacecraft magnetic field component By 1pe15.8 spacecraft magnetic field component Bz 1pe15.8 spacecraft magnetic field component Bmag 1pe15.8 total magnetic field strength rms_Bx 1pe15.8 rms mag component rms_By 1pe15.8 rms mag component rms_Bz 1pe15.8 rms mag component npts i4 number of points in average Data Files (.TAB extension) =============================================================================== Name Records Cols Len Start Stop ------------------------------------------------------------------------------- T790226 12093 12 127 1979-02-26T00:00:35.897Z 1979-03-04T23:59:47.925Z T790305 12142 12 127 1979-03-05T00:00:35.925Z 1979-03-11T23:59:56.059Z T790312 12131 12 127 1979-03-12T00:00:44.059Z 1979-03-18T23:59:56.236Z T790319 10607 12 127 1979-03-19T00:00:44.236Z 1979-03-24T22:49:32.304Z =============================================================================== MAX/MIN Statistics for: T790226 ------------------------------------------------------------------------------- :::::::::::::: T790226.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: 12 --------- Aggregate Statistics ---------- Total number of records: 12093 /======================================================================\ | COLUMN | MINIMUM | MAXIMUM | AVERAGE | #
