L20030916_00021:28:30Taking background data for chopper characterization70EG
Think I'm seeing increased chopper jitter- the motor is
probably worn out.
L20030916_00021:51:31Stopped taking background data, starting normal data acq0EG

L20030916_00023:54:14Changed the chopper altitude , was seeing signal induced noise10330EG
L20030916_00101:01:15Some cirrus at 10km on and off during the run, thikness9400EG
increasing lately.

L20030917_00004:18:14Ending normal data taking11130EG
L20030917_00004:18:47Taking a look at the TX halfwave plate, it might need optimizing11500EG
L20030917_00004:19:42changed HWP mode to flipping, adjusting plate for min TX11500EG
L20030917_00004:27:29Done optimizing, taking a few records to see10490EG
