Figure 10. Humidity stimulation expressed as saturation deficit.

Effect of temperature on the parameters of the regression plane utilized to determine the response characteristic of the moist cell (A) and the dry cell (B) to oscillating changes in the saturation deficit. Aa and Ba: yo intercept of the regression plane with the F axis reflecting the height of the regression plane plotted as function of temperature. Ab and Bb. Gain for the rate of change of the saturation deficit plotted as function of temperature. Ac and Bc. Gain for the instantaneous saturation deficit plotted as function of temperature. Relationships approximated by linear regressions [f = yo+aT]. R², coefficient of determination; the number of points per plot was 30. Arrows point in the direction of increasing axis values. F impulse frequency, SD saturation deficit.
