Determine tlag from uncorrected fit to the beta exponential function. The name tLag is a misnomer. It simply is the maximum of the PDR curve, so in papers by Bluck et al. it is renamed to tMax. Maes B D, Ghoos Y F, Rutgeerts P J, Hiele M I, Geypens B and Vantrappen G 1994 Dig. Dis. Sci. 39 S104-6

`cf`	named vector of coefficients; only `k` and `beta` are required Note that `k` is measured in 1/min (e.g. 0.01/min), usually it is quoted as 1/h (e.g. 0.6/h).

lag time as defined from Maes fit
