     Thanks for responding to that so quickly, Kasimir.  It should save Olaf
some time.

     Did you just use a boxcar average?  If so, it will have significant
(I'd guess a peak of about 2% of true amplitude) Gibbs ringing in the
result, but given the erratic quality of the source data (i.e., the mix
of varying lengths of records, times of day, and so forth) and given how
the results will be used, it's probably no big deal, and no one is likely
to realize the ringing is present when they look at a graph of it anyway.
How many 15-minute periods wide is the window?
