Issue DM-3984: Errors for shear bias fits
DM-1135 mostly was inconclusive or at least not highly significant, due to the fact that the error bars were around the same size as the differences in most of the tests. This in spite of the fact that we ran 6x as many sample galaxies as great3sims. Investigate the reason for this, and see if we can estimate the errors more accurately. Investigate what the best way (or at least the way it is done in GREAT3) to estimate the errors on the bias parameters. If it is not from the covariance matrix of the regression parameters, there could be some work here.
