[visad] using ErrorEstimate


I'm trying to figure out how to use ErrorEstimate-s. I have simple time series data as FlatField-s (time -> value) to do some math on and I'd like to propagate some errors. The reality is that I have an array of values and an array (of the same size) of variances.

Do I need to construct an ErrorEstimate[] to pass to setRangeErrors? If so, how? I don't see a constructor that makes sense. I simply want to say, "here are the variances for each of my values."
