AN EVALUATION OF THE 1965.0 EPOCH, H. O. 1706 WORLD MAGNETIC VARIATION CHART.
Abstract
An evaluation of the 1965.0 epoch, H. O. 1706 World Magnetic Variation Chart is performed by direct comparison of charted and observed values. Results of this study provide an estimate of chart reliability based on the correlation of the computed spherical harmonic surface and individual field data values. (Author)
