Changes to _get_iv to compute covariant errors

5

Added changes to the function _get_iv in optimize.py - placed each unit flux model in a corresponding image - calculated Fisher information matrix F - found the covariance matrix C...

combine overlapping sources in FIM, stable covariance

2

In the original variance_update branch, the major failure mode is the inversion of Fisher information matrix (FIM) caused by perfectly overlapping sources. If there are any such sources in a...
