### Curious about deconvolution

Posted:

**Thu May 26, 2016 8:43 pm**Hi,

(not sure this is the right forum to post my question...)

I was wondering if there is an optimal setting for the Radius parameter (Decon module) linked to the image scale (arcsec/pixel) and seeing for deconvolving an image. If I am not mistaken, the Radius should somehow control the size of the point spread function (PSF) used by the module, and then one would like to have it tuned such that its size matches the seeing. Alternatively, it could be tempting to run some blind deconvolution on a smaller area of the image just to estimate the "true" PSF, and then use it for deconvolving the whole image...

Thanks!

Nico
