        K2flix makes it easy to inspect the CCD pixel data
        obtained by NASA's `Kepler <http://keplerscience.nasa.gov>`_
        and `TESS <https://tess.gsfc.nasa.gov>`_ space telescopes.
        
        The need for this tool arises from the fact that all telescope data is
        affected by sources of noise such as pointing jitter and foreground asteroids,
        which are often more easily spotted by eye than by algorithm.
        
        This tool takes Kepler's or TESS's *Target Pixel Files (TPF)* as input
        and turns them into contrast-stretched animated gifs or MPEG-4 movies.
        These *TPF files* are publically available from the 
        `Kepler archive <https://archive.stsci.edu/missions/kepler/target_pixel_files/>`_,
        the `K2 archive <https://archive.stsci.edu/missions/k2/target_pixel_files/>`_,
        or TESS simulations. 
        
        K2flix can be used both as a command-line tool or using its Python API.
        
        Example
        -------
        Asteroids commonly pass in front of Kepler/K2 targets. 
        We can use k2flix to create a two-day animation of pixel data to view the asteroids whizzing past::
        
            $ k2flix --start 545 --stop 680 --step 1 --fps 12 --stretch linear --ut http://archive.stsci.edu\
            /missions/k2/target_pixel_files/c1/201500000/72000/ktwo201572338-c01_lpd-targ.fits.gz

        Installation
        ------------
        If you have a working installation of Python on your system, you can install k2flix using pip::
        
          $ pip install k2flix
        
        Alternatively, you can get the latest version by installing from source::
        
          $ git clone https://github.com/barentsen/k2flix.git
          $ cd k2flix
          $ python setup.py install
        
        Using k2flix
        ------------
        After installation, the `k2flix` tool will be available on the command line. You can then use it as follows.
        
        To convert a Kepler pixel file to an animated gif::
        
          $ k2flix tpf-file.fits.gz
        
        To convert a Kepler pixel file to an MPEG-4 movie::
        
          $ k2flix --o movie.mp4 tpf-file.fits.gz
        
        K2flix supports reading from web URLs, so you can generate a movie directly from the data archive::
          
          $ k2flix https://archive.stsci.edu/missions/k2/target_pixel_files/c1/201400000/00000/ktwo201400022-c01_lpd-targ.fits.gz
        
        
        To see all the options, use the `--help` argument to see the full usage information::
            
            $ k2flix --help
            usage: k2flix [-h] [-v] [--output FILENAME] [--start START] [--stop STOP]
