Those who use a photon-counting photomultiplier tube, the conventional
"high-speed photometry" in white light would have the advantage in terms
of high signal-to-noise ratio and the time resolution. Slow changes in
the source intrinsic variablity and atmosphere could be removed by using
simlutaneously planned CCD photometry.
