Factory for simple Gaussian PSF models Provides a high-level interface to DoubleGaussianPsf and SingleGaussianPsf by specifying Gaussian PSF model width in FWHM instead of sigma, and supporting computing kernel size as a multiple of PSF width. This makes it suitable for tasks where PSF width is not known in advance.

Construct a GaussianPsf Parameters ---------- fwhm : `float` FWHM of core of star (pixels); if None then self.defaultFwhm is used Returns ------- DoubleGaussianPsf : ``lsst.meas.algorithms.DoubleGaussianPsf`` Returns if self.addWing is True SingleGaussianPsf : ``lsst.meas.algorithms.SingleGaussianPsf`` Returns if self.addWing is False

Compute kernel size and star width as sigma. The kernel size will be odd unless minSize or maxSize is used and that value is even. Assumes a valid config. Parameters ---------- fwhm : `float` FWHM of core star (pixels); if None then defaultFwhm is used Returns ------- size : `int` Kernel size (width == height) in pixels sigma : `float` Sigma equivalent to supplied FWHM, assuming a Gaussian (pixels)
