with Hirata-san, Fabian-san and checked by Miyoki-san
We removed four parts of FC on the HR surface and inspected it using green light.
Some FC stains could be cleaned successfully but unfortunately, some FC residues were still on the circumference line of the first FC.
It was not perfect, but we decided to finish this cleaning work.
Please confirm each picture.
