21. The calibration curve in the inset in Fig. 2 is a phenomenological fit, and our conclusions are independent of its details. In particular Fig. 2 is self-similar if one assumes a uniform transfer rate h=kx, with a different k coefficient.

24. A slight reduction of the h (y) slope with increasing x above yt, has more probably to do with different mobilities of hO and hCa, rather than with the above mentioned trimer formation threshold.
