LineList

class specviz.core.linelist.LineList(table=None, name=None, masked=None)

Bases: astropy.table.table.Table

A list of emission/absorption lines

Parameters:

• table (Table) – If specified, a table to initialize from.
• name (str) – The name of the list.
• masked (bool) – If true, a masked table is used.

Methods Summary

extract_range(wrange)	Builds a LineList instance out of self, with
extract_rows(indices)	Builds a LineList instance out of self, with
merge(lists)	Executes a ‘vstack’ of all input lists, and then sorts the result by the wavelength column.

Methods Documentation

extract_range(wrange)

Builds a LineList instance out of self, with the subset of lines that fall within the wavelength range defined by ‘wmin’ and ‘wmax’

Parameters:wrange ((float, float)) – minimum and maximum wavelength of the wavelength range Returns:line list with subset of lines Return type:LineList

extract_rows(indices)

Builds a LineList instance out of self, with the subset of lines pointed by ‘indices’

Parameters:indices ([QModelIndex, ..]) – List of QModelIndex instances to extract from. Returns:line list with subset of lines Return type:LineList

classmethod merge(lists)

Executes a ‘vstack’ of all input lists, and then sorts the result by the wavelength column.

Parameters:lists ([LineList, ..]) – list of LineList instances Returns:merged line list Return type:LineList
