Notes. The CWL (center wavelength at normal incidence), Tpeak (peak transmission), and FWHM values are measured from the profiles plotted in Fig. 3. Part numbers were assigned by the manufacturer. PC: Calibrated telescope polarization model exists. The numbers in parentheses correspond to filters not currently installed in the CRISP filter wheel. Compare with Table A.1 in the CRISPRED paper.
