These are idealized thicknesses used earlier in the mission.

These are the thicknesses of the flight filters. These were read
off of the Luxell filter certification sheets. The serial numbers
are identified as flight according to the "as-run" notes from when
the filters were installed.

For these numbers, the "as-flown" thicknesses are reduced by arbitrary
oxide thicknesses, wehere appropriate. These are the final values
used for estimating the filter responses. (NB: Still looking for
the Luxell entrance filter sheet.)
