      Description

      In order to evaluate the instrument throughput, please examine the defocus image to measure the obscuration by detector, spider, etc. It would be good to start from DCB images but this may depend on illumination pattern and should change as a function of the location of the PFI focal plane. The current ETC assumes 15% regardless of the position on the focal plane.
