The diffpy.labpdfproc.functions module provides tools
for computing and applying absorption correction (cve) to 1D diffraction patterns.
Gridded_circle: This class supports absorption correction by creating a uniform grid of points within a circle for a given radius and mu (linear absorption coefficient), and computing the path length and effective volume for each grid point at a given angle.compute_cve: This function computes the absorption correction curve for a given mu*D (absorption coefficient mu and capillary diameter D). For brute force computation, it averages the effective volume across all grid points, then computes the cve values as the reciprocal of this average. For polynomial interpolation, it uses pre-computed coefficients to quickly interpolate cve values for a given mu*D. Polynomial interpolation is available for mu*D values between 0.5-6.apply_corr: This function applies the computed absorption correction to the input diffraction pattern by multiplying it with the computed cve, resulting in a corrected diffraction pattern.
