We updated the PCAL library to inlcude calibration of temperature and OFS gain channels and rename OPTICALFOLLOWERSERVOOSCILLATOR channel to OPTICALFOLLOWERSERVOOSCILLATION. We committed the changes and restarted EPICS database to update these changes. After that we burtrestored h1ecatx1 and h1ecaty1 to an earlier time this morning. Everthing seemed went fine.
