****************************************************** PR # 21130 ASCA observation of QSOs near PKS0237-233 is proposed. Within 2 degrees from PKS0237-233, there is a concentration of 32 QSOs with z = 0.17 - 2.63. The purpose of observation is acquire energy spectra of distant "normal"(not OVVs nor BL Lacs) QSOs effectively to under stand their evolution and contribution for CXB in 2 - 10keV range. ******************************************************
