Notes: Estimate of dispersion (S), based on the transformation of Cox (1970) = 20.4°. N = number of determinations within each unit. Point inc = estimation of the inclination mean based on the averaging method of McFadden and Reid (1982). Inc95 = estimation of 95% confidence interval of inclination. k = estimate of precision parameter. — = not applicable. N for "Average" values is the estimated number of independent time units (see text).
