      Description

      As described in the report from July 5, 2018 (https://www.overleaf.com/17550215gqrxkdfywqkp#/66627172/) PSF of the data taken at LAM exhibit more scattered light than expected. One possible contribution is scattering caused by the grating. I plan to estimate how does this contribution look like by modeling the effect as described in http://adsabs.harvard.edu/abs/2008MNRAS.386...47E   (Equations 16 and 18).  Paper which explicitly talks about gratings of PFS is http://adsabs.harvard.edu/abs/2014SPIE.9147E..5XB
