Examples of how to run ProFit on multi images, be they offset images with the same filter, or multi band. The final example shows it working in a highly automated mode, extracting PSFs and fitting a smooth model across bands without sharp discontinuities.
Here we look at how to simultaneously fit multiple images of the same object. Each one can have a different PSF and segmentation map etc. This is a better route to multi-exposure fitting than just stacking.
Almost fully automated fitting. This is useful for beginners finding their feet, and particularly easy cases.
Example of complex multi-band stacking including dynamic masking.

Example of calculating a filter transform using ProSpect. In this case we use Sloan r and i to predict VST r.
A simple example of generating fake data and then fitting it. The latter part should get people started with fitting a real galaxy.
A good starting document for the new user of ProFound.
Here we use ProSpect to generate the EBL with a model for the SFH and ZH.

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.
