Attached are plots of dust counts > .5 microns in particles per cubic foot. Also included are plots of the modes for a particle counter in the optics labs, LVEA and end Y. The plot of the mode of the dust monitor in the optics lab (H0:PEM-LAB_DST1_MODE) shows approximately when the communication was lost and restored for the three dust monitors in optics lab, vacuum prep, and bake oven room.
