The first section describes the finite difference approximation of the conservation of volume equation, the second describes how the regularization parameter, alpha, is chosen and how uncertainties are estimated, and the third describes the effects of over or under smoothing when alpha is not its optimal value. 1. text01.pdf Text and figure describing methods and uncertainty estimation 2. fs01.tif High-resolution version of Figure S1.
