EOF plot

Wilfried,

the option "-neof" specifies how many of the leading EOFs shall be
computed -- not to compute only the n-th EOF!  Eofgrads  always
display the first EOF.  To see the others, you need to open the output
descriptor file.  For more information see
http://www.atmos.ucla.edu/~munnich/Grads/EOF.
