    5151 * hard limit on number of inputs (was shell descriptors limit of 1024 easily being reached with image,mask,weight,psf,cmf files for each input. Raised to 65535 now by default.)
    5252 * selection of target PSF FWHM, worse input PSF not necessarily best choice as could end up being rejected and only a few inputs may be that large (not representative)
    53  * heavy RAM use (10-20GB typical for 100+ inputs)
    54  * long run-time for 20+ inputs, 400 inputs order 12-14hr (use method similar to psphotStack?)
     53 * heavy RAM use (10-20GB typical for 100+ inputs) -- tests run unoptimized, will need to look at effect

    375375== Target PSF: manually set and as not worst input image ==

    377 want to look at NOT setting the convolved stack target PSF based on the worst input.
    378 
    379 have seen cases when the worse inputs are image rejected so in that case not a good idea to use anyways.

    380378 * for large N, a rerun would be of little time cost or just reject outright as little input to final stack
    381379 * for small N may want to reject anyways
    382380 * instead of a rerun of target psf, could choose median psf or such and use poorer deconvolution to reject worse images anyways

    384384TODO
    385  * will need to make a sample distribution of simulated PSFs, currently sample is flat. revise the making of the stack.mdc list of inputs
     385 * will need to make a sample distribution of simulated PSFs, currently sample is flat. revise the making of the stack.mdc list of inputs. or will just be worse/upper limit of possible stack degrading for including deconvolved images.

     387SYS.ERR=0 change set, but effect comes after this stage so not important.
