The amplitude differences between CCD and PMT measurements.

KANAAN A., O'DONOGHUE D., KLEINMAN S.J., KRZESINSKI J., KOESTER D. and DREIZLER S.

Abstract (from CDS):

Using model atmospheres, quantum efficiency and transmission curves, we compute expected values for amplitudes of DAV, DBV and DOV stellar models as measured through different detectors and/or filter combinations. We conclude that choosing the wrong detector may lead to amplitudes lower by 20 % than those measured by phototubes. The correct choice of CCD + filter may reduce this problem down to a difference of 6 %.
