replace removed scipy.interpolate.spline
scipy.interpolate.spline
was deprecated in 0.19.0
and removed in 1.3.0
see here.
This is used for the calibration plotting.
I updated the call to scipy.interpolate.spline
to use scipy.interpolate.interp1d
.
This is the same method as is used in the calibration module.
We may want to make a change down the line to make the plotting use the code from the calibration module.
This is currently broken in the current ligo cvmfs builds so we should fix ASAP.
