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:

wavQuantity

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

factornumpy:array_like

If wav is a |Unit| instead of a |Quantity| then factor is the value wav will be multiplied with to convert it to a |Quantity|.

Deprecated since version 7.0: factor is deprecated. Pass in wav as a |Quantity|, not as a |Unit|.
