[PIPE2D-1051] Taper off transmission at dichroic boundary

Fri, 13 Jan 2023 01:00:05 +0000

As discussed during the last SPS telecon 2022-06-01 and DRP telecon 2022-06-03:

For SM3, the dichroic transition at the red end for the r detector is in the wrong place, which affects the image quality on the low transmission side.

Instead of relying on the physical properties of the dichroic, Implement a software solution that tapers off the transmission, using eg a Fermi-Dirac function.
