Response of AD10 at OD = 5.3 to a stepped intensity pattern. a Normalised quantities as indicated vs. x after ≈30 min of stepped illumination, and predictions for normalised ρs based on two speeds (dotted line) and complete measured \(\bar v(x)\) profile (dashed line). Error bars are s.e.m. of the y-averaged values. b Time dependence of normalised \(\rho^{\mathrm{s}} \bar v\) at various x (see legend). The sample was uniformly illuminated before the halves pattern was switched on at \(t = 0\). In both plots the grey area corresponds to the standard deviation in experimental values for uniform illumination (\(t < 0\))
