I don't know why i wrote the replicate command in my original post...
I did not use replicate in my code!
Anyway, I would prefer to bin rather than interpolate, because I would
like to reduce my noise (t1 is much more finely sampled than t2 so
averaging many t1 points rather than interpolating should help)

But for quick and dirty analysis, I will use INTERPOL as a fast fix.
Thanks for the suggestion.

I'm still on the lookout for a clever array solution...

take care,
james
