L20020205_00022:35:48Start of experiment0EG
01:20:57Tweeked sodium HG as energy had fallen during warmup0EG
L20020206_00203:09:42Signals look good and the sky is clear0EG
L20020206_00405:30:00Sodium layer changing shape0JJ
L20020206_00709:35:34Just noticed that the sodium channel crashed0JJ
When deselecting Run the following error message poped up
GPIB error in uGPIB. Threadibsta=49408 Threadiberr=6
After hitting the OK button on the error dialog and
selecting Run things were fine again....
15:34:25checkigng a potential error in the data aq0EG
15:40:43Restarted the program, the data from the time of the error0EG
is probably damgaed.
23:00:33Soem haxe has crept in 0EG
L20020206_00623:21:51clouds getting thicker0EG
01:21:06Heavy clouds ave moved in and we have no signal now0EG
03:45:09A noisy reckord on the Rayleigh channel0EG
03:55:41Sodium had drifted to 589.155nm, tuned to 589.158nm0EG
03:58:08It has been clearing up a bit so there is useful data comming in0EG
now.
05:33:09timegaps between records may have increased a bit for the 0EG
past few minutes as I had to steel CPU cycles to salvage
IRIS data.
