John Samson Nov 9, 2015
Particle size range 5um - 400 um
Treshold 105 
those settings were used for all processing 
(first few files were processed with 3 um min setting - but produced about 10 higher count in lowest bin - suspected out of focus particles, counted noise)
Then all were reprocessed with the same settings. Old Nov 9 files with 3 um min setting were deleted.
