Correction for Scherrer et al., Characterizing sliding and rolling contacts between single particles

The authors note that Eqs. ( 2) and (4) appeared incorrectly."In the case of Eq. ( 2), the current version of the equation is not dimensionally correct, i.e., the torque M 0 must be divided by R p too to ensure correct dimensionality.In the case of Eq. ( 4), the symbol 1 should appear on the other side of the equality.The first error causes the units of part of Eq. ( 2) to be erroneous, but it does not affect any of the following results or conclusions of the manuscript.The second error would lead a reader to the wrong calculation of the values of 1 .However, repeating the derivation of the force and torque balance from Eq.(3) based on the geometry displayed in Fig. 2 would lead to the correct solution.We used the correct derivation in all the following parts of the manuscript that use the values of 1 for further calculations.This is just a typo in the equation and does not affect the reported data."On page 3, Eq. ( 2) should instead be written as:
