L10114023:56:02Haze present44540EG
L10114000:00:47Tuning for maximum sodium44540EG
L10114000:15:08Done tuning maximum as regstered on wavemeter is 589.15745570EG
to 589.158nm. Incremented
L10115000:15:54Counts45570EG
L10115000:19:59Rayleigh Convergence mirror adjusted40220EG
L10115000:22:06The Rayleigh counts seem a bit low compared to the nice35290EG
clear skies, Opening the iris a little more to see if that helps
any.
L10115000:25:06No impact seen on the counts.0EG
L10115000:51:21Tweeked the dye HG as it was not warm when I started taking0EG
data.
L10115000:58:16Changing the HG seems to have affected the tuning slightly0EG
tuned -1pm resulting in higher count,s continuing to find
max again.
L10115001:15:36there is an enhanchment on the sodium layer at ~89km 53630EG
L10115001:17:35Regarding the dye laser tuning, not much tuning done. The54220EG
system was apparently close to max, See wavelogfile for
amount of tuning done.
L10115001:34:03Looks like there is a small kink in the rayleigh profile at 0EG
~50km.
