Filtered and Decimated Magnetic Field Data


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

Time span: 1971-07-31 to 1971-08-15


This data set consists of a sample BCD magnetic tape containing filtered and decimated magnetic field data as submitted by the experimenter. The tape contains a header record and successive groups of 3 physical records, where each such group constitutes one logical record. The 1602-character header record includes the degree of decimation and the filter weights used. The first physical record in each logical record contains the time of the first subsequent vector. The second and third physical records each contain 50 magnetic vectors, (Cartesian components in ALSEP coordinates and field magnitude). NSSDC will hold a list of times for which the original data were subject to filtering and decimation and will acquire appropriate tapes from the experimenter as request activity warrants.
