摘要:
Differentiation of these formulae with respect tozyields the higher vertical derivatives directly from the observed anomalies. The methods include allowance for local variations in the density of observation points, and are designed to prepare data for the drawing of contour maps on a uniform basis by mechanical means; of the two methods that of the exponential filter exhibits much greater numerical stability in handling irregularly distributed observations.
