string name = 'HSM Psf FWHM'
 
float pixelScale = 0.168
 
int SIGMA2FWHM = 2*np.sqrt(2*np.log(2))
 

Detailed Description

Functor to calculate the PSF FWHM with second moments measured from the
HsmShapeAlgorithm plugin.

This is in units of arcseconds, and assumes the hsc_rings_v1 skymap pixel
scale of 0.168 arcseconds/pixel.

Notes
-----
This conversion assumes the PSF is Gaussian, which is not always the case.
