But, the sign of alpha dependency (curvature) is opposite @r=200mm. Small offset which is depends on field radius (linear, quadratic, and cubic - linear is some of scale change, cubic is distortion error, quadratic is not natural in optical calculation) may explain observed flux attenuation around a dot, but I can not find exact mechanism of alpha-dependency.</cite></p> Relates PIPE2D-1217 Development Rank 0|zzsy33:
