Problem reading in data longer than 180 elements
I'm having a strange problem where the I'm reading in a numpy array that has 201 elements, but only the first 180 elements of that array are accepted and have a fit run on them.
I'm attaching the data file and minimum working example.
IIRrational.__version__
'2.5.1'
$ python -V
Python 3.7.9
EDIT: attaching nominal transfer function measurement
