Known issues

Currently this only works with data taken with the Cosmic Origins Spectrograph (COS) aboard the Hubble Space Telescope, and many of the peculiarities, both in plotting and scraping the headers for information, are particular to COS. That said, it does work for all COS data, both in the FUV and NUV, publicly available as of February 2016.
