Coefficients of variation. A. The cvs for nine model parameters inferred from one cycle (red) and three cycles (white) of DD data. B. A heat map showing −l o g(c v) for all parameters and cycle lengths on the colour scale white (low cv) through to red (high cv). C. The cvs for model parameters v
for constant darkness (DD), 8, 12 and 16 hour days, inferred from 1 and from 5 cycles of data. D. Calculated log Z values for 1–5 cycles of DD data. The maximum log Z in each series (cycle length) is set to 0 to facilitate comparison.
