Just a couple of updates.

BSM_S is now operational.  Peter has worked out the last bugs, and data is flowing.  The first order of business was to process the backlog of science data that has been taken during the commissioning phase.

OC61 is nearly operational.  We now have the software talking to all of the hardware.  The camera does not come into focus as the back focal distance changed when we put the new camera on, so Nigel Frost will be modifying the camera mounting to solve this issue.  There are some startup/shutdown scripts to modify, and the webcam needs to be repositioned.  My guess is about a week to start commissioning the system.  The QHY600 camera has a smaller field of view (14x9arcmin instead of 14x14 arcmin), but it has twice the QE, reads out much faster, has far better readnoise, and doesn't have the RBI problem of the old camera.  The loss of a small amount of field won't be missed much, and if necessary, we can put in a focal reducer.

The northeastern weather pattern of rain and clouds has broken, and BSM_NH2 should be producing more data.

I'm now getting "BSM-S4" images from May in my VPhot account.  I'm eager to catch up with these old images, but there are no Transforms for this system in the Telescope Setup files.  Is S4 the same as S2?  Can I use the S2 transforms until the S4 transforms are added to the Setup files?

Updated transform coeffs now exist. See separate post.
