Data loaded from detarred, dezipped files from the DMF

To reduce Operator need for frequent filter changes, dilution turned on @ 14-02-21 21:12.  Every 24-h, the dilution is turned off for 5 minutes.  This was not long enough to get an undiluted sample.  

As always, data not reported for T(blue) < 0.7

Impactor in place.  HOWEVER, signal wired backwards until 2014-06-19 20:00.  The 10 and 1 in the primary data files (on the master\impactor) are reversed.  As cofirmation, the flow signal decreases slightly when the impactor is in the 1-um state.  The data polarity problem was corrected in software (leading to the correct polarity signal being recorded) on 2014-06-19 20:00:28.  For this month, the problem was corrected here in the Mentor QA/QC'd data files using: 

root:psap_out:impactor = root:inputfolder:wave11==10 ? 1 : (root:inputfolder:wave11==1 ? 10 : root:inputfolder:wave11)

and the following notation put in Comment 1:  DQR D140703.2 Impactor polarity reversed in raw file until 2014-06-19 20:00:28.  Corrected here.

2014-04-29 02:32:48, 2014-05-02 21:27 DQR D141017.15 The 'Master' computer went into a state of constant reboot.  This disrupted the impactor control.  It is unclear what state the impactor was in during this period.  

Some evidence of supermicron particles.  A number of local events resulting in high absorbance.  These were not edited.
