[gradsusr] gr2stn() doesn't match plot

[Miquel Bernis]

Hi everyone,

I'm running grads 2.0.a9 on a Virtual Machine Ubuntu 12.04

I'm sorry because I'm new using the software and maybe this is a quite
basic question. I would like to ask you about the function gr2stn(), my
problem is that when I try to compare the results of ploting any variable,
with the results of using gr2stn for an specific point doesn't seem to
match. Using the example model.ctl of the basic grads tutorial it seems
that tsfc-273 on the label 1000 rounds 10 degrees (more or less) on 42N 2E,
but when I lock lat and lon, the result of using gr2stn() get me to a 26.8,
which is no quite the expected. It's the same in other labels, variables,
and even with other files. Does anybody know what I'm doing wrong?

Thanks for reading. I would appreciate your help.
Miquel
