Fig. 2: Growth kinetics of individual pits.

Plots of pit volume as a function of exposure time are provided for six pits in (a) and (b). Note the split in the x-axis between 90 h and 1110 h for (b). c Highlights a change in growth rate for pit 4, see boxed area in (b). Error bars represent measurement uncertainty in volume and time as described in the “Methods”.
