To follow up my recent e-mail. As it turned out, the abs was turned on
on Friday. However, the pid loop for the transitions was not turned
on. Hence, the target was badly detuned. In a sence we were running
upol target. Please mark runs 8733-8738 8740 8742-8746 8748-8755
8757-8764 8767-8772 in the logbook accordingly.

The target seems to work now, at least I see transitions. However, a
background is very high. The ligit is reading1.5e-7 which is twice the
usual value. This needs to be addressed at some point.
