... In the aberrated PSFs, they affected the diffraction ring structures, and in the corrected ones, they cause scattering which ... In narrow-band filters, where the PSF does not change much over the bandpass, the diffraction rings are sharp. ...
... This method does not rely on simultaneous measurement of the sky spectrum with the ob ject spectrum. ... Fitting the first 710 of these eigenvectors using svdres removes the rest of the sky features from our ob ject+sky spectrum. ...
