L20030206_00522:04:11Not all that linear! requires further study1130EG
L20030206_00522:04:28stopped data aq to change into normal mode0EG
L20030206_00522:09:53Started data aq again in normal data aq mode 0EG
L20030206_00522:16:29UPS! RX halfwave plate was not connected. moved the 0EG
plate manually and reconnected the plate motor.
L20030206_00522:18:18beutinful clear night out there 9990EG
L20030206_00522:26:28UPS! Note Range on Reyleigh upto now is wrong due to 0EG
changes in trigger source during chopper charateriation.
trigger source chnaged back to the Q-sw out, incremented.
