Description: # 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](figure1.png "An example of using plot_fits with matplotlib")
        
        
        ## 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`.
