Hello,
I have worked a bit on simulated images with sourcextractor++ and while the model-fitting usually retrieved values close to the parameters used to build the images, the difference between data…

Hi,
I do not understand why you are running a loop on phi, which does not contain any parameter varying with phi? Why not using a single theta variation, the use the axy-symmetry of the situation to …

I installed source extractor using brew on Mac.
I am trying to use with the default configuration files, but error appears.
Fitting model: background offset+point source+Sersic spheroid+exponential …

Sersic and/or moffat profiles come to mind. If we couple the Gaussian variance to any other data-redux parameters, e.g., source extraction radius, we'd need something similar for these profiles.

I'd like to give a good sense of how common various assumptions/lazy approximations about morphology are in the extragalactic community, so in your reading over the next few weeks could you remember t…

Just a note that R200 would be useful to have in the FoF data output for scaling.
We could probably do with some other parameters carried through, but that's one that I just went to look for.

I am working on well resolved nearby galaxies and the availability of the priors is great!
However, other models would be better suited for spiral galaxies than Sersic (disk with inner/outer trunca…

Hey, I was trying to create a mock image with the ImageModel class. It does work with a Pseudo Jaffe profile, but I am getting this error when I try with a NFW_MC profile -
