Figure cont.2 :
Transmission of Contamination Layer.
The top plot shows the measured spectrum of the Ti anode
at two times, 9611 and 9810, about two years apart.
The bottom panel shows the ratio of these spectra - presumably
this is the transmission of the contamination layer on the SSD.
For comparison, the solid line shows the
transmission of a layer which is 40% transparent and 60%
covered by 3 micron thick polyimide.
