UV, ultraviolet; the prefix d indicates depressed sensitivity (see text for an explanation).

R5-8 characteristics were obtained in the present study (bold). Others are based on data reported by Qiu et al.(2002) and Qiu and Arikawa(2003).

Data for R9 was reported by Shimohigashi and Tominaga(1991).
