Hourly Averaged Magnetic Field Vectors

Description

This hourly averaged vector data set is on a magnetic tape written in binary on an IBM 360 computer with each physical record containing the hourly averages for 1 day. The first three words of each physical record are the year, month, and day; the remaining words are stored in a matrix 14 x n where each column of 14 words contains all the information for one hourly average. That information includes hour (starting time) of the first average, number of 30-s averages in the hour, number of data points, hourly averages of the X, Y, Z components of the magnetic field and magnetic field intensity, standard deviation for X, Y, and Z, and hourly averages of standard deviation delta X of X, delta Y of Y, and delta Z of Z components for 30-s averages. All quantities are in a solar-ecliptic frame of reference (X-axis toward the sun) centered on the spacecraft. All field quantities are given in units of nanoteslas.
