• Constants a and b were determined by least squares fit of the equation ae−by2to the SAI response profiles for the seven cylinders. Fvalues were calculated by dividing the regression mean square by the residual mean square; the high F values indicate the close fit (all p << 0.001; n, number of data points. The width of the profile at half-height w = 1.67/√b.
