Attached are plots of dust counts > .3 microns and > .5 microns in particles per cubic foot from approximately 5 PM Jan. 17 to 5 PM Jan. 18. Also attached are plots of the modes to show when they were running/acquiring data. Dust monitor 10 in the H1 PSL enclosure is still indicating a calibration failure. The plots of the status gave a 'No data output' error, but I'm not sure what it means, since plots were generated and look reasonable.
