I'm not even sure if I could do this, but I'll give it a try.. It's ackward since
I'll have to eventually read in another 3 data sets with similar properties, and
I'd much rather handle 4 big arrays than 80 little ones. It's my own brain I'm
worried about, not the computer's!

I think my problem may be that my array is not consistent. I can apply one filter
to the flight# (3-19 only), but I cannot apply a single filter to the point
number, since this varies from flight to flight. On flight 3, there may only be 10
data points, but flight 4 may have 12, flight 4 21, etc...

Perhaps I am misunderstanding the usage of the filter. Am I producing seperate
filters for each dimension (hence the problem above), or am I producing a global
filter for the entire array (which treats entries individually, and not genrically
by dimension)?
