Hi Valentijn-

Sample is a VisAD RealTuple instead of a Real.

The parentheses are the result of the toString method of
the RealTuple.  If there were multiple components (e.g.
u and v wind components), then it would have them separated 
by commas within the parens.

Try Sample[0].getValue()= or Sample.getComponent(0).getValue(),
or Sample.getRealComponents()[0].  If the brackets ([]) don't
work, try replacing them with parens (I'm no jython expert).

In general, you should check on the type of the object
that is being return and do the appropriate call to
get the actual value.  These probes will always return
VisAD Data objects, not numbers.  Depending on the
probe, you could get back a FieldImpl, a FlatField, 
a RealTuple or a Real.

That would require changing the toString method on all VisAD Data objects
(which we can't do), so try the methods above.
