Purpose : Rutine data collection
Date(s) : 000306 - 000306
File(s) : L3060 - L3063
Comments : Don't know why but I can't find any signal in the sodium channel. Going to do
rayleigh only tonight.

L306000:06:12Start of experiment1640JJ
L306000:10:55No signal in sodium channel for onknow reason0JJ
L306001:02:14Opening iris to 2mm, incremented1
L306101:03:14Tweeked the Rayleigh50671
L306101:45:26Sodium on line now, there are noise problems probably 1
due to the HWP controller, reestarting ARCVI program
without the HWP controller on
L306101:47:54System pause restarting program1
L306101:49:12Started data collection again without HWP tracking57392
L306202:01:25No improvement. may be the radar that's doing this2
disconnected leads from the monitoor scope (sodium)
L306202:14:29UPS! changed sodium recs. scan to 600, incremented2
L306302:15:59Moved the chopper delay upwards2
L306303:04:54looks like the removeal of the scope connection did something2
to lower the noise by facto 10. Gong to put them on again
to see if the noise increases
L306303:05:58scope leads back on2
L306303:08:47took scope leads off again as the noise came back2
L306303:12:23slight haze at a low altitude2
