Oops. The checkfir() function obviously gives only a valid noise figure for the
case of linear interpolation. To get a valid figure for cubic interpolation,
you'll need to compare with a more precise (5th order interpolation or exact)
method, and I am not sure that comparison in the center of the interval is a
representative test in this case.
