Notes. 1 For Band A and B, the fractional RMS of the red noise is 0.2 and 0.03, respectively, analogous to red noise from X-rays and optical. The slope of the red noise is -2 for both.
2 Using reasonable values, analogous to the new technology telescope (NTT) at La Silla, Chile (Tarenghi & Wilson 1989):
Telescope diameter = 3.58 m; Telescope altitude = 2400 m; Exposure time = Time resolution-1.5 ms (i.e. ‘Deadtime’ of 1.5 ms); Target altitude = 40|$^\circ$|; Turbulence height = 8000; Empirical coefficient C|$_{Y}$| = 1.5.
3 Frequency at which the phase lag is be assumed to be correct (i.e. not shifted by |$\pm 2\pi$|)
