Inspection of the O1 showed a small doughnut shaped water spot about 2 inches N-NW of the center of the occulter. There was a cloud of a dozen of small spots about 1 inch from the edge near he East edge. There was also some residue near West and south, both of these were close enough to the edge that they may have been under the aperture stop. I believe lens artifacts show up in the opposite side of the kcor FOV. So the water spot would show up in the S-SE side. I dont think we have a good radial mapping for how far in the FOV an artifact will show up. Previous work with lens suggests to me that only the center ~4 inches contribute to bullet holes to kcor images. I dont think the artifact in the outer inch of the lens contiubte to bullet holes. I am sure they contribute to the background levels and may cause other images issues (that arent artifacts). All that said I don't think I see a clear mapping between stuff on the lens and issues in the kcor images. Washing with soap and water appears to clean up all of the artifacts described above. ___end___ GENERAL COMMENT BY berkey: Tue Jun 15 03:24:13 GMT 2021 Cirrus moved in and is too thick to take kcor data so we cannot test the lens cleaning. ___end___ ONSITE STAFF: berkey, lisapg
