I dunno the answer to Tom's question. However, 3-4 hours is enough to
give a quite sensitive detection - assuming there's a signal to be had -
for these high frequencies. Thus, a reasonable observing strategy is to
do the fast sampling say one night a week (and lose a little sleep that
night), and spend the rest of the time with some more judicious choice
that will let you sleep.
When the fast signals reappear, then it's different - then we need some
long adjacent nights with fast sampling (and excellent timekeeping of
course) to determine the new period, etc. My quick analysis suggests
they haven't reappeared yet.
