5.1.5 sd.linecatalog - Tool

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:

row index in the table
name of the species
line frequency
frequency error
line intensity

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.

Arguments


Inputs
name	Name of the catalog
	allowed:	string
	Default:

Example

        l = sd.linecatalog(’jpl_asap.tbl’)
        # set name restriction
        l.set_name(’NH3’)
        # print summary
        l.summary()
