!Release notes for ACIS-S Optical Blocking Filter (OBF) Optical Diffuse Transmission. !12 August 1998, G. Chartas / Penn State University ! !Filename: !acis_s_trans_dif_898.qdp ! !Format: !ASCII table. There are 2 columns: !1) Wavelength (angstroms) !2) Optical Transmission of ACIS-S OBF in the range between ! 2.8000e+03 and 1.1975e+04 angstroms for diffuse light. ! ! Description: ! The diffuse transmission, T_diff, through the ACIS UV/Optical filters was calculated using ! the expression: ! ! T_diff(lambda) = Sum[W(theta_n-1,theta_n)*T(theta_n-1,theta_n,lambda)] / Sum[W(theta_n-1,theta_n)] ! ! where W(theta_n-1,theta_n) = cos(theta_n-1) - cos(theta_n), is a weighting function that takes ! into account the differential solid angle that the filter `sees' for incident photon angles ! between theta_n and theta_n-1. ! T(theta_n-1,theta_n,lambda) is the optical transmission for rays incident at an angle of ! theta_n-1. ! !
