Custom pinhole smearing is broken?

[Federica Sebastiani]

Federica Sebastian - student at LU noticed a problem with the custom smearing in SasView? 4.0.1 …

Setting values in custom pinhole smearing gives a different answer to loading the same values from a data file.

Some instruments do not provide resolution information - hence the need for the custom smearing.

Taking data set and calculating a, say, 8% dQ/Q and putting that in the file as the 4th column behaves as expected.

Generating a custom pinhole smear with *the same dQ_low and dQ_high* as the dataset with "fake" resolution column gives a completely different answer and blows the curve out.

Attached images are for the attached data set with
(a) resolution from dQ data which was faked in the file.
(b) resolution from a custom pinhole smear using the same dQ_low and dQ_high
