Description: Install
        =======
        
        Try install many of the scripts with
        
        ::
        
            pip install astro-scripts
        
        This is still under development though, but it does work!
        
        To check the installation run ``plot_fits`` in the terminal.
        
        WARNING
        =======
        
        Look at the wiki instead:
        https://github.com/DanielAndreasen/astro\_scripts/wiki It's not done,
        but I will gradually move documentation to the wiki.
        
        Small tools for an astronomer
        =============================
        
        Small scripts to make my life easier.
        
        The tools are mainly (if not exclusive) for spectroscopy. All the small
        scripts are fairly well documented, and the python scripts use the
        module ``argparse`` which means you can run them like
        
        ::
        
            python numpy2moog -h
        
        and get some fancy help information on how to use them. The shell
        scripts have a block comment in top of the file.
        
        I recommend putting this folder in your PATH so the scripts are easily
        accesible. To do so depends on your system. I am sure
        `google <http://www.google.com>`__ can help you ;)
        
        Dependencies
        ------------
        
        -  `Matplotlib <http://matplotlib.org/>`__
        -  `Astropy <http://astropy.org>`__
        -  `numpy <http://numpy.org>`__
        -  `argparse <https://docs.python.org/3/library/argparse.html>`__
        -  `PyAstronomy <http://www.hs.uni-hamburg.de/DE/Ins/Per/Czesla/PyA/PyA/index.html>`__
        
        plot\_fits
        ----------
        
        This I find to be a very powerful and handy python script. It simply
        plot a fits file and leave you in pan mode (matplotlib). More over it
        has the feature to plot a part of the solar spectrum and telluric lines,
        and finally redshift the spectrum.
        
        For this script one needs to use the telluric and solar spectrum
        provided here and change the path in ``plot_fits`` in line 46 and line
        57.
        
        The wavelength vector is created from the fits (which should be 1D). It
        uses the keywords - CRVAL1: The beginning of the wavelength. - CDELT1:
        The step in wavelength. - NAXIS: The length of the wavelength vector.

           Example
        numpy2moog
        ----------
        
        This is a python script that converts ASCII arrays into the format for
        `MOOG <http://www.as.utexas.edu/~chris/moog.html]>`__. It can be a bit
        tricky, but I will provide examples in the future.
        
        VALDextraction
        --------------
        
        This script is used to send emails to ``extract all`` from the VALD
        database. A central wavelength should be inputted with the ``-h`` flag,
        and the half range should be given with the ``-s`` flag.
        
        Example
        ^^^^^^^
        
        ::
        
            VALDextraction -w 6743 -s 3
        
        This will open a new email (Thunderbird) with the syntax required for
        VALD (no reason to delete the signature) in a 6Å window centered on the
        wavelength 6743Å.
        
        splotCommenter.sh
        -----------------
        
        This one-liner I have saved in a script put a ``#`` on all the lines
        containing a ``center`` from a IRAF files after using the ``splot``
        routine. This allows to easy read the ``splot.log`` with python using
        something like ``np.loadtxt``. One probably need to remove date strings.
        This should be easy to implement I guess.
        
        VALDprepare.sh
        --------------
        
        This bash script unpack a linelist from
        `VALD <http://vald.astro.univie.ac.at/~vald3/php/vald.php>`__ when the
        download option is set to FTP. The downloadable file is ``.gz``. This
        file is unpacked and saved in an optional ``output`` argument (see the
        block comment in the script). The references is saved in a seperate
        file, and the final file is relatively easy to read with ``np.loadtxt``.
