      Description

      In DM-2914 (specifically, in 73ed9bc8) a change was made to the calculation of variance.

      This is incorrect: while deblending does split up the noise part of the pixel values as it splits up the signal, we don't want to account for that in the variance plane, because we're even more uncertain about value of deblended pixels than we are unblended pixels. Please revert it.

      This is a port of HSC-1334.
