Trended the dust the dust monitors in the LVEA for the past 30 days, 7 days, and 1 day as a base line for the vent. The three dust monitors in the LVEA are:

   #2 in HAM1/2 cleanroom
   #6 in HAM5/6 cleanroom
   #30 in Biergarten for BSC3

   I have posted the 30 and 1 day plots. The data older than 24 ago, for the 0.3u on DM #2 is bogus. Since there is nothing interesting in the 7 day plot it was not posted.
