OK, are you sure, then, that this isn't a byte order
problem? When you read the data, do the minimum
and maximum values look OK to you? Are they in the
range you expect? Have you put them in a variable
that maintains all the precision of the data?
Have you tried plotting the data as points instead
of contouring it? Does it still look reasonable?

Have you printed out t and r to see if those values
look OK? Have you tried to display Z1 as a surface?

Still a lot of possibilities left... :-)

Cheers,

David
