a A grid map of the f value for the parameter spaces of horizontal locations. The thick frame indicates 95% confidence interval estimated from the F test (Árnadóttir and Segall 1994). b Same as a for the parameter spaces of S–N location and depth. c Same as a for the parameter spaces of equatorial and polar radii at each optimal pressure change. The number indicates optimal pressure increase in MPa, and calculation did not converge for the cells without number
