PSF musings by Dan Taranu
Here we look at fitting a region of overlapping sources, using ProFit to improve our initial photometry from ProFound.
A complex example combining the outputs of ProFound with the inputs of ProFit.
ProFound segmentation maps dissected in detail.
A simulated example of stacking images using ProFound.
Main overview of the ProFound source finding package.
Examples and tests of the ProFound sky estimation routines.
Testing ProFound on simulated images.
A demo of using extracted isophotal ellipses to fit a basic 1D profile, and using these fit parameters to make reasonable estimates for a full 2D ProFit solution.
This is a demo of using ProFit in a fully automatic mode for processing VST data in the SAMI clusters.
Basic overview of the package that accompanies the GitHub version of the code. This covers basic installation issues that you might have.
In this vignette we fit a model Moffat profile fit to an empirical PSF. We then use this model PSF for our image convolution when fitting a galaxy, rather than the empirical estimate that comes packaged with ProFit.
This vignette concentrates on the model image generation capabilities of ProFit, ending with examples of producing images with dozens of galaxies distributed around a large frame.
This vignette lets the user try a sophisticated decomposition of 10 example galaxies that have both SDSS and KiDS data. These examples were presented in the original ProFit MNRAS 2017 paper.
Some info on speeding things up by making use of OpenCL and OpenMP support.
A detailed vignette on what we mean by, and how to construct, sigma maps.
