You can key in the wavelength and desired residual phase from the Properties and Inputs page, brought up using the right mouse button in the RH window. Recommended Cal Time is calculated using the equation for t cyc , below. No Paging switches off the 1-min display changes. This should be good to 1 km, but gets hairy beyond that depending on behaviour of the structure function that we don't measure. To change the wavelength, key in a wavelength on the Properties and Inputs page, brought up using the right mouse button in the window.
Red bar highlights the present value of saturation rms phase.
Each window cycles through its displays, changing each minute. The other windows will continue to display real-time data until you select a date in them as well. Likewise, the coherence function will continue to display current data because the plots are not logged. It is derived every 10 min from the most recent 10-min of phase time series. Calibration cycle time is probably the quantity you require for observing.
