The :command:`goettingen_to_specint` tool extracts a flux spectrum from a data file in FITS format (with the schema described by :ads_citealp:`husser:2013`), and writes it to a :f-schema:`specint` file. This tool accepts the following command-line arguments:
.. program:: goettingen_to_specint
.. option:: <fits_file_name> Name of input FITS file.
.. option:: <wave_type>
Type of wavelength abscissa. This determines the number and
distribution of points to assume for the input file. Supported
options, corresponding to the different grids described by
:ads_citet:`husser:2013`, are :code:`HiRes` (high-resolution),
:code:`MedRes-A1` (medium-resolution, :math:`\Delta \lambda =
1\,\angstrom`) and :code:`MedRes-R10000` (medium resolution,
:math:`\mathcal{R}=10\,000`).
.. option:: <specint_file_name> Name of output :f-schema:`specint` file.
Note
In order for :command:`goettingen_to_specint` to build, you must first uncomment/edit the line in :file:`$MSG_DIR/build/Makefile` that defines the FITS_LDFLAGS variable. This variable defines the flags used to link against your system's FITS library.
