        # twirl
        
        twirl is a python-only astrometric plate solving package. It is suited for cases where the RA-DEC coordinate of the image center is known and a WCS needs to be computed easily.
        
        twirl is based on the algorithm of Lang et al. 2009 (astrometry.net) and go through these steps:
        1. detection of stars in the image if not provided
        2. catalog query using image known center
        3. 4-points asterisms building and matching following Lang et al. 2009
        4. image recombination and wcs fit (astropy.wcs)
        
        ## Example
        ```python
        import twirl
        
        stars = twirl.find_peaks(data)[0:15]
        radec = twirl.gaia_radec(target, shape, pixel)
        wcs, aligned = twirl.match_wcs(stars, radec, return_aligned=True)
        ```
        More examples are provided in [docs/notebooks](https://github.com/lgrcia/twirl/tree/master/docs/notebooks)
        
        ## Installation
        
        For now twirl needs to be installed locally (soon pip installable)
        ```shell
        git clone https://github.com/lgrcia/twirl.git
        python3 -m pip install -e twirl
        ```
