Getting started
**********************

Installation
============

Requirements:

* PySM 3 `PySM <https://github.com/healpy/pysm>`_
* healpy

Install with `pip` from Github::

    pip install https://github.com/simonsobs/so_pysm_models/archive/master.zip

Development installation
========================

Clone from Github and install::

    git clone https://github.com/simonsobs/so_pysm_models
    cd so_pysm_models
    pip install -e .

Run unit tests::

    python setup.py test -V

Build docs::

    python setup.py build_docs -w
    
Example Usage
=============

This repository implements new models for PySM that can be added as additional components.

For example, create and configure a component::

    from so_pysm_models import GaussianSynchrotron
    synchrotron = GaussianSynchrotron(nside = 16)
    
Create a PySM sky and add this component::

    sky = pysm.Sky(nside=64, component_objects=[synchrotron])

Then get a map at a specific frequency in GHz with standard PySM functionalities::

    import astropy.units as u
    m_synch = sky.get_emission(2.3 * u.GHz)
