Those measures was been made on images taken with a 200 mm lens, f/3.5, on a 35 mm film Fujy NPH 400 ISO, exposure 3 minutes. HYAFK=GSC 5427:1699 8.9-10.2 p LB Type 20020211.887 7.567 p TSc (+/-0.44) 20020211.891 7.642 p TSc (+/-0.41) This mesures seem overestimated, but the LB (pulsating) type can to justfy this value.
