    I plotted your flash measurements, and found them to be very accurate.
    The spread is +-0.04 s, of which at least +-0.03 s is due to timing
    resolution and/or image frequency/exposure time.
    Using 4.702 s period, it is obvious that the first and last flash is
    part of a main sequence, of which only flash #4 is missing.
    The secondary maxima lack the last five flashes. (Graph 92-85A.gif sent
    to yK)
    Plotting 2.351 s period you can see that the secondary maxima are about
    .04 s after the mid-period, getting slightly closer by the end.
    (92-85A2.gif )
    The 4.4 s you refer to (old observation?) is very reasonable, assuming
    it also used the full period, or the secondaries couldn't be seen.
    My (attempt of) PPAS report was made with the help of PPASinp.exe v.2,
