[ncl-talk] covariance_query

[Dennis Shea]

[1] warning:escovc: Non-fatal conditions encountered in series or xstd = 0.0

This is a 'warning' that a particular series had all constant values. Hence
its standard deviation is 0.0.
--------------------
[2] All that look like

(0)    is_valid_latlon2d_attr: Warning: The 'lat2d' attribute must either
be  ....

are from graphics ... NOT from: ccv = escovc(CoD_final,ccr(:,:,0))

(0)    *Error: scalar_field: If the input data is 1-dimensional, you must
set sfXArray and sfYArray to 1-dimensional arrays of the same length.*

Again from graphics
