Methods Documentation

convert_units_to_strings(unit_list)[source] [edit on github]

Convert equivalencies into readable versions of the units.

Parameters

unit_listlist: List of either astropy.units or strings that can be converted to astropy.units.

Returns

list: A list of the units with their best (i.e., most readable) string version.

create_flux_equivalencies_list()[source] [edit on github]: Gets all possible conversions for flux from current flux units.

create_spectral_equivalencies_list()[source] [edit on github]: Gets all possible conversions from current spectral_axis_unit.

process_unit_conversion(spectrum, new_flux=None, new_spectral_axis=None)[source] [edit on github]

Parameters

spectrumspecutils.Spectrum1D: The spectrum that will have its units converted.
new_flux: The flux of spectrum will be converted to these units if they are provided.
new_spectral_axis: The spectral_axis of spectrum will be converted to these units if they are provided.

Returns

converted_spectrumspecutils.Spectrum1D: A new spectrum with converted units.

set_spectrum(spectrum, label)[source] [edit on github]

Set spectrum for unit conversion.

Parameters

update_ui()[source] [edit on github]: Set up UI to have all values of currently visible spectra.

vue_unit_conversion(*args, **kwargs)[source] [edit on github]: Runs when the apply button is hit. Tries to change units if new units are set and are valid.
