--- Comment #2 from Michael Brewer <brewer at astro.umass.edu> ---
Following this logic, if my data set consisted of less than 201 samples, KST
would display nothing. In my opinion, the INDEX vector should always extend to
one point beyond the number of frames (or partial frames) present in the data
set to capture all of the data that the user may be interested in. It is like
the X axis on a plot which should extend slightly past the end of the data.
Another way to look at this is that each frame represents a unit of time (one
second in my case). If I have 10 seconds of data, then the INDEX field shoold
extend from 0 seconds to 10 seconds, not from 0 seconds to 9 seconds.

In fact, my data set contains fields with different sample rates. Most of the
data is sampled at 200 Hz. But some of it is sampled at 10 Hz and some at 1 Hz.
Extending the INDEX vector by 1 would capture all of this data.
