do you need to know the noise model to make the noise model?

Description

we assume we know something, namely a white noise model specified by ivar maps, to get properly weighted map differences.

how hard would it be to generalize this, eg first to a strawman model? would this help anything (eg noise from map differences vs. autos minus crosses)?

Research direction

Start by reviewing how ivar maps currently provide the white-noise model for weighted map differences. Compare that assumption with the proposed strawman model and with noise estimates from map differences versus autos minus crosses. Done should mean a defined generalization path and a clear assessment of whether it improves the noise model.
