spectral_density

astropy.units.equivalencies.spectral_density(wav, factor=None)

Returns a list of equivalence pairs that handle spectral density with regard to wavelength and frequency.

Parameters:

wav : Quantity

Quantity associated with values being converted (e.g., wavelength or frequency).

Notes

The factor argument is left for backward-compatibility with the syntax spectral_density(unit, factor) but users are encouraged to use spectral_density(factor * unit) instead.
