ProSpect: Filter Transforms
Example of calculating a filter transform using ProSpect. In this case we use Sloan r and i to predict VST r.
ProSpect: Simple Fitting
A simple example of generating fake data and then fitting it. The latter part should get people started with fitting a real galaxy.
ProFound: Tips and Tricks
A good starting document for the new user of ProFound.
ProSpect: Extra Galactic Background Light
Here we use ProSpect to generate the EBL with a model for the SFH and ZH.
Prior Knowledge
A short journey into the use and impact of priors on LML and Bayes Factors.
ProFound - Colour Me Happy
A short vignette showing how to do forced, or semi-forced (encouraged?) colour photometry.
ProSpect - BC03 vs EMILES
Comparison of BC03 and EMILES SSPs
ProSpect - BC03 Checks
Some sanity checks of the BC03 library.
ProSpect - Introduction
A short guide and basic introduction for beginners to ProSpect. This is likely to evolve with time.
ProFit - PSF Convolution Can Be Convoluted
PSF musings by Dan Taranu
ProFound/ProFit - A Complex Fit
Here we look at fitting a region of overlapping sources, using ProFit to improve our initial photometry from ProFound.
ProFit/ProFound - The Full Monty
A complex example combining the outputs of ProFound with the inputs of ProFit.
ProFound - Segim Maps
ProFound segmentation maps dissected in detail.
ProFound - Stacking Images
A simulated example of stacking images using ProFound.
ProFound - Source Finding
Main overview of the ProFound source finding package.
ProFound - Sky Shenanigans
Examples and tests of the ProFound sky estimation routines.
ProFound - Simulated Images
Testing ProFound on simulated images.
ProFit/ProFound - Using Isophotal Ellipses
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.
SAMI Cluster Demo
This is a demo of using ProFit in a fully automatic mode for processing VST data in the SAMI clusters.
ProFit - GitHub README & Installation Instructions
Basic overview of the package that accompanies the GitHub version of the code. This covers basic installation issues that you might have.
ProFit - PSF Fitting
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.
ProFit - Make Model Image
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.
ProFit - Galaxy Fitting Example
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.
ProFit - OpenCL and OpenMP
Some info on speeding things up by making use of OpenCL and OpenMP support.
ProFit - Sigma Maps
A detailed vignette on what we mean by, and how to construct, sigma maps.
