available_linelists()

erase_spectral_lines(name=None, name_rest=None, show_none=True)

Erase either all spectral lines, all spectral lines sharing the same name (e.g. ‘He II’) or a specific name-rest value combination (e.g. ‘HE II 1640.5’, stored in SpectralLine as ‘table_index’).

load_line_list(line_table, replace=False, return_table=False, show=True)

plot_spectral_line(line, global_redshift=None, plot_units=None, **kwargs)

Deprecated since version 5.2: The plot_spectral_line function is deprecated and may be removed in a future version. Use plot_spectral_lines instead.

plot_spectral_lines(line=None, global_redshift=None, colors=None, plot_units=None, show_all=True, **kwargs)

Plot either a single spectral line or the set loaded in self.spectral_lines.

If line is provided (a table row, a string index/linename, or a QTable), the function will plot that specific line(s). If line is None, the function behaves like the old plot_spectral_lines and draws all rows.

Examples:

Plot all lines:

plot_spectral_lines()

Plot a single line by name:

plot_spectral_lines(line=’Halpha’) plot_spectral_lines(‘Halpha’)

Plot all lines with custom redshift:

plot_spectral_lines(global_redshift=0.01)
