[ferret_users] Modulo axis question

[Roman Tonkonojenkov <romantonk@xxxxxxx>]

Dear Ferreters,

I have a question about modulo axis and hope that
somebody competent can comment on this.
When I load up a NetCDF file, I get
the following error:
 *** NOTE: Ignored modulo length exceeding axis
length: XT
Would anyone be able to explain to me what this means and if this
is an error?

Any comments would be very appreciated,
Many
thanks,
Roman

   Axis span (to cell edges) = 360 (modulo length = axis span)

double XT(XT) ;
