Please fix.</p> PIPE2D-816

Correct for fraction of light from a source entering a fibre

N.b. there's a typo in the manual to make things harder (should be zeta = 4/((1 - upsilon) D) on page 21).</p> <p><a href="https://github.com/Subaru-PFS/spt_ExposureTimeCalculator/blob/master/src/gsetc.c#L504" class="external-link" rel="nofollow">https://github.com/Subaru-PFS/spt_ExposureTimeCalculator/blob/master/src/gsetc.c#L504</a></p> Development Rank 0|02qpjd:00r20060i20018001 Sprint 2DDRP-2021 A5 2DDRP-2021 A 6 2DDRP-2021 A 7 2DDRP-2021 A 8 Story Points 2.0
