Hi Ken,
I thought depth_time was 2d but I see its not. Anyway here is the
result of help:
IDL> help, temp, time, depth
TEMP STRUCT = -> <Anonymous> Array[1]
TIME STRUCT = -> <Anonymous> Array[1]
DEPTH STRUCT = -> <Anonymous> Array[1]
I thought this would work for vectors but I get:
IDL> contour, temp,time,depth, /Irregular
% CONTOUR: Struct expression not allowed in this context: TIME.
% Execution halted at: $MAIN$
One thing to note is that this is a very large dataset, with depth,
time, and temp all FLOAT[392197].
Cheers,
Mat
