Perhaps a long shot, but does anyone still have a copy of the full source code archive for IRAF v2.16 (or any earlier version back to around 2008-9 would probably do) including the stsdas/contrib stuff? Also ideally the code that used to be available at ftp://ecf.hq.eso.org/rhook/cplucy ? I'm trying to understand their implementation of PLUCY and CPLUCY with a view to further improvements to Siril's deconvolution code. If anyone has a copy they'd be willing to put on a filehost and PM me a link, I'd be very grateful.
