      Description

      We've found on HSC that we do need more than 16 mask planes, and hence it's almost certain that LSST will as well. We might as well make that change sooner than later.

      This will also make it a bit more important that we get FITS compression working (there is code to do this, but we don't know how recently we've used it).

            The work to increase the number of bits to 32 has been done, but the compression work has not.

            Please attach the compression ticket to this RFC then. It currently looks like all the work has been completed.

            I don't see a statement on this RFC that implementing it requires compression. I think it's done.

            I'm fine with closing this (hurrah!), but the implication was that we'd almost immediately get compression enabled as otherwise we have a significant regression (both in disk storage and possibly I/O rates). So can we make it a reasonably high priority?
