    keyword=Mirror missing from PREX detector in 8/25 tests

    The 45 deg. angled configuration of the PREX detector did not have any mirror installed on the holder between the quartz face and the PMT. The exact effects of this are unknown and require cosmics tests, but presumably the lack of mirrored surface lowered the mean we found for number of channels.
