The following changes should be made to the paper, “Computer simulation of low‐frequency electromagnetic data acquisition” by W. A. San Filipo and G. W. Hohmann (Geophysics, September 1983, p. 1219–1232). The equation for the vertical magnetic induction in gammas over a conductive half‐space for a vertical time‐harmonic dipole (p. 1221) should be: [Formula: see text] The computed signals used in the examples are correct, as can be verified by the initial value (on‐time primary field) of the time‐domain response shown in Figure 15.
