L20041111_00005:55:33Start of experiment1090EG
Small hole, or so i thought! Rather thick uniform low
altitude clouds in the way
L20041111_00006:23:23looked like I had some signal induced noise up to this point3720EG
closed the receiver lid and signal looks ok now.
L20041111_00006:24:13No chance of verifying halfvave plate orthogonality now5090EG
to much variability in the signal due to clouds to do any tweeking
L20041111_00006:31:45Moving chopper to t lower opening altitude, it's a bit high0EG
