- IterativeGaussianWBackground.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
