Processing Record for this file: (Make notes here unique for this file) Loading 4/1 - 4/16/2014 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. The 10 and 1 in the primary data files are reversed. This has been 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: Impactor polarity reversed in raw file. Corrected here. Some evidence of supermicron particles. A number of local events resulting in high absorbance. These were not edited.
