Elixir-Tools
This section describes basic Elixir tools provided by Ohana. These include a set of FITS file interaction programs (fields, fhead, ftable, fits_insert), a few data analysis tools (gastro, gastro2, mosastro, imclean), and a variety of other useful for astronomy and data-handling programs.
