Hi Frank,

I hope I'm interpreting your question correctly ...

The OPeNDAP protocol only supports sequential and regularly spaced array
index requests, e.g.:

- every point from index 0 thru 12 -- [0:1:12]
  (0, 6, 12, 18, 24, 30, 36, 42, 48, 54, 60, 66, 72)

- every 5th point from index 2 thru 12 -- [2:5:12]
  (12, 42, 72)

If you want a list of index points that doesn't fit one of the above
patters, you would need to either extract additional points that you
actually want or make multiple requests.
