L991004023:08:18Start of experiment0KR
L991004023:10:37Running w/out Dye beam expander, tuning Dye by Na ratio.22370KR
L991004023:11:29Haze layer22370KR
L991004023:19:17Tuning Na --> 589.018 dye fundamental, ratio 0.13 47000KR
L991004023:40:23Still tuning... Haze is clearing out.49390KR
L991004023:50:49Is that a little sporadic Na layer I see?53510KR
L991004023:54:44It's some kind of layer, too bad I'm still tuning...54300KR
L991004023:56:50Pretty well tuned, I think, ratio 0.98. I've stopped fiddling.52660KR
L991004001:03:47Sodium Convergence mirror adjusted50980KR
L991004001:04:43Tuned Na wavelength -0.5 pm, looks like I had been off a tad:51620KR
ratio now 1.13
L991004102:03:24Just noticed data taking has been stopped for 20 min 'cause51030KR
Na trigger not getting through. Incremented filenum,
set Na SR430 to trigger off Rayleigh for now.
L991005102:15:46Some interlock was cause?? Trying to figure out what to50700KR
do about it.
L991005202:26:42Reset dye keyswitch, everything back on line, don't know51710KR
why. Incremented filenumber.
L991005202:31:59Sodium Convergence mirror adjusted, 51720KR
Dye system tuned to 589.158 nm on wavemeter
