Calculating Phase Shifts
With the onset
times identified, least-squares fits to the onsets have been calculated
for two
different time periods. Shift-Clicking on the actogram within the raster
for a given day will now display the time delay between the two fitted
lines extrapolated to that day. Here, for example, the phase shift of 2.24
hours is being displayed for line 30. The TAU's for the two fits, here
23.6 and 23.75 hours, are also displayed for the user (not shown). Setting
up the fits and displaying the phase difference takes only a
few mouse clicks.
