Window Removed
Removed 1064/532 beam splitter
L20080507_00205:27:13Tweaked the second Iris and did some converging.0
Rayleigh profile looks okay now. Near field spike is no longer
an issue. Cabinet door is still open => Noise on 607nm channel.
L20080507_00205:41:45Put in daystar filter. Tweaked it a bit.0
L20080507_00206:35:06Jan has been in and out of room for past 30 minutes0
background0
L20080507_00206:55:38Raman signal has been getting worse - could be related to the 0
increase in background as the sun rises
L20080507_00206:56:45Daystar in Rayleigh channel is performing well 0
L20080507_00206:58:40Too much background in Raman signal must shutdown0
this channel SZA=87.27 degrees
L20080507_00207:08:39running only Rayleigh now after I placed the cover over the0
PMT and stopped teh Raman program
L20080507_00307:34:30Rayleigh signal reaching noise floor near 60 km sza=84.340
Daystar still in path
