The settling velocity (Eq. (3) on page 4) should be negative. In previous papers we have included the negative sign as part of the parameter in the tables, but this isn’t how it is handled in the code, in the optimization, nor in the rest of this paper. The negative sign is built into the code and the parameter is just the magnitude of the settling velocity. In this paper, I used the previous formulation of the equation but expressed the parameter value as it is input to the code. To correct the discrepancy in the two there needs to be a negative sign here in Eq. (3). The suggested change is the smaller change that also corresponds to how the negative sign is handled in the code itself. Ultimately, there is a typo that needs to be corrected.
