 """Runs get_trilegal perl script; optionally saves output into .h5 file Depends on a perl script provided by L. Girardi; calls the web form simulation, downloads the file, and (optionally) converts to HDF format. Uses A_V at infinity from :func:`utils.get_AV_infinity`. .. note:: Would be desirable to re-write the get_trilegal script all in python. :param filename: Desired output filename. If extension not provided, it will be added. :param ra,dec: Coordinates (ecliptic) for line-of-sight simulation. :param folder: (optional) Folder to which to save file. *Acknowledged, file control in this function is a bit wonky.* :param filterset: (optional) Filter set for which to call TRILEGAL. :param area: (optional) Area of TRILEGAL simulation [sq. deg] :param maglim: (optional) Limiting magnitude in first mag (by default will be Kepler band) If want to limit in different band, then you have to got directly to the ``get_trilegal`` perl script. :param binaries: (optional) Whether to have TRILEGAL include binary stars. Default ``False``. :param trilegal_version: (optional) Default ``'1.6'``. :param sigma_AV: (optional) Fractional spread in A_V along the line of sight. :param convert_h5: (optional) If true, text file downloaded from TRILEGAL will be converted into a ``pandas.DataFrame`` stored in an HDF file, with ``'df'`` path.
