sas.sascalc.corfunc.corfunc_calculator module

This module implements corfunc

class sas.sascalc.corfunc.corfunc_calculator.CorfuncCalculator(data=None, lowerq=None, upperq=None, scale=1)

Bases: object

compute_background(upperq=None)

Compute the background level from the Porod region of the data

compute_extrapolation()

Extrapolate and interpolate scattering data

Returns:The extrapolated data

compute_transform(extrapolation, trans_type, background=None, completefn=None, updatefn=None)

Transform an extrapolated scattering curve into a correlation function.

Parameters:

• extrapolation – The extrapolated data
• background – The background value (if not provided, previously calculated value will be used)
• extrap_fn – A callable function representing the extraoplated data
• completefn – The function to call when the transform calculation is complete
• updatefn – The function to call to update the GUI with the status of the transform calculation

Returns:

The transformed data

extract_parameters(transformed_data)

Extract the interesting measurements from a correlation function

Parameters:transformed_data – Fourier transformation of the extrapolated data

set_data(data, scale=1)

Prepares the data for analysis

Returns:new_data = data * scale - background

stop_transform()

transform_isrunning()

sas.sascalc.corfunc.transform_thread module

class sas.sascalc.corfunc.transform_thread.FourierThread(raw_data, extrapolated_data, bg, updatefn=None, completefn=None)

Bases: sas.sascalc.data_util.calcthread.CalcThread
