We don't yet know what our favored measurement is.
PROS
wmom: lowest noise in recovered shear by a big factor (about 2 I recall)
pgauss: it is pre psf so it may provide better colors. may have less variation with seeing
CONS
wmom: not pre psf so will vary with seeing and may not provide as good colors
pgauss: much noisier
Given that we can't decide between these yet, it seems useful to allow more than one to be measured and stored so we can compare them.
