     339Odd streaks seem more common in 1D convolved stacking when should be plenty of inputs to reject pixels.

    341345Appears that the .exp. files for the >30 input stacks are mostly NAN. Suspect the compression had a problem. Has been happening for over a year. Added a .EXP.NOCOMP option (one already existed for EXPWT) and if a stack is made uncompressed (as is with deep stacks) then this is used.

    345351r35925 appears to produce similar rejection to the original ISIS method, and includes a fix the the other rejection issue found in the night stack sample below. Target PSF for convolved stack is now set to the max FWHM of the input warps that pass all input cuts with an additional epsilon of 0.1 pixels.

    386393Configuration modifications for PV2 and 1D convolution should probably be applied to nightly stacks as well as other additions
