      Description

      The canonexp readout and mcs exposure processing take significantly more time than we want, and can be made more efficient. As it stands a single 0.8s exposure takes more than 10s. From looking at the timings, three obvious improvements are:

      • run the canonexp library routines in a permanently running daemon, which can pipe N*0.8s reads to the mcsActor without going to disk.
      • likewise, write the PFSC files in a background process, so that nothing waits on the writes.
      • mask off the non-PFI parts of the image and otherwise tune the background subtraction and centroiding.

      This ticket addresses the first of these improvements.
