Today we reviewed the height of the mirror in the context of measuring its pitch with thelaser level. When the BF was at the setpoint and the mirror was at the correct height, the LVDT readout was 7440 counts not 10467 counts as reported before (see notebook). We need to double check. It's important to point out that the SF LVDT is not calibrated and the LVDT readout is always in number of counts, not um as I had written in previous reports.
