IterativeGeneralizedGaussianWBackground.determine_size()

Sets the size for the kernel based on the width of the PSF.

This is defined as

\[s=\text{floor}(4*\text{max}(\sigma_x, \sigma_y)+0.5))\]

which corresponds roughly to the size required to capture at least 2 sigma of the PSF along its widest axis, or 95.45% of the curve.

Return type:

None
