Line catalog
Description

The linecatalog is a wrapper for line catalog data base. These can be either ASCII tables or the tables saved from this class. The table consists of the following items:

The user can filter lines by name, frequency range, or intensity range. It is possible to overlay line catalog on the spectral plot using plotter.plot_lines.

For ASCII type input table, Comments can be present through lines starting with ’#’.

The constructor takes string that specifies a name of the catalog.

Known Issues

The name of species canno’t contain spaces. If it does, it has to be wrapped in double-quotes.
