|
| |
| double | getSigma2 () const |
| | Return the radius of the outer Gaussian. More...
|
| |
| double | getB () const |
| | Return the ratio of Gaussian peak amplitudes: outer/inner. More...
|
| |
| bool | isPersistable () const noexcept override |
| | Whether this Psf is persistable (always true for DoubleGaussianPsf). More...
