We proceeded with section 14 Focal Plane Transmissions. The throughput of the filters was measured relative to the open/open configuration. This was done for Al-K, C-K, O-K, and (the start of the) Mo-L X-ray sources (sections 14.1 to 14.4).

A table of the peak transmission rates for the completed source sets is shown here. Each dark-subtracted image maximum was divided by the exposure duration.
