[ncl-talk] help-about "esacr"

[Dennis Shea]

I am not sure of the question. The esacr function documentation:

     http://www.ncl.ucar.edu/Document/Functions/Built-in/esacr.shtml

includes the following

mxlag

A scalar integer. It is recommended that 0 <= mxlag <= N/4. This is because
the correlation algorithm(s) use N rather than (N-k) values in the
denominator (Chatfield Chapter 4).
