The non-parametric MCCD PSF modelling, or MCCD for short, is a Point Spread Function modelling pure python package. It is used to generate a PSF model based on stars observations in the field of view. Once trained, the MCCD PSF model can then recover the PSF at any position in the field of view.
## Contents
1. [Dependencies](#Dependencies) 1. [Installation](#Installation) 1. [Recomendations](#Recomendations)
## Dependencies
The following python packages should be installed with their specific dependencies:
[numpy](https://github.com/numpy/numpy)
[scipy](https://github.com/scipy/scipy)
[astropy](https://github.com/astropy/astropy)
[ModOpt](https://github.com/CEA-COSMIC/ModOpt)
[PySAP](https://github.com/CEA-COSMIC/pysap)
It is of utmost importance that the PySAP package is correctly installed as we will be using the wavelet transforms provided by it.
## Installation
After installing all the dependencies one can perform the MCCD package installation:
#### Locally `bash git clone https://github.com/CosmoStat/mccd.git cd mccd python setup.py install `
To verify that the PySAP package is correctly installed and that the MCCD package is accesing the needed wavelet transforms one can run: python setup.py test and check that all the tests are passed.
#### From Pypi `bash pip install mccd `
## Recomendations
A useful example notebook testing-simulated-data.ipynb can be found [here](https://github.com/CosmoStat/mccd/tree/master/notebooks).
Quick tutorial will be written soon as well as examples on how to run the MCCD PSF modelling on real images using as input SExtractor catalogs.
