Brett, I'll have to look at how the missing values are handled. I'll look at interpolating the AVN thinned to the CED grid you mention. I know I had the program issue a warning if the output grid had points outside the original domain- which would be possible with the ETA, but the AVN is global...assuming all 8 parts of the grid have been received, so this should not be a problem unless there is a seaming problem.
