The refcav transmission has been decaying quickly over the last day or so (down to about 0.7), and we've been getting a warning about the transmission being too low on DIAG_MAIN.  I took a few mins between locks to tourch it up briefly, now it's at about 0.76.  So, not a major improvement, but at least gets us away from the threshold we'd set for ourselves that we know is bad.  This should (hopefully) get us through the long weekend, and then later we can revisit whether or not we need to do any in-enclosure alignment during the break.
