# spectral_density

astropy.units.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.
