Brief question involving optfir.low_pass()

Is there any way to determine the order of the filter that
optfir.low_pass()
is generating in any given case? It works properly, but knowing the
order
would be beneficial to my group’s documentation.

optfir.low_pass() returns the coefficients for the desired filter, use
the
python len() method to get the number of taps.
