Attached are plots of dust counts requested from 5 PM April 8 to 5 PM April 9. There seems to be a large spike in > .3 micron counts at end Y from ~ 2 AM - 3 AM, and a smaller corresponding spike at end X.
The times appear to be wrong towards the ends of these plots. There should be a gap in the data due to a DAQ restart. This can be seen from the fact that the number of minutes does not go to 1440. This was realized in comparing these plots to those produced by dataviewer.
