The Spectrum1D object to which the smoothing will be applied.

width : number

The width of the median filter in pixels.

Returns:

spectrum : Spectrum1D

Output Spectrum1D which is copy of the one passed in with the updated flux.

Raises:

ValueError

In the case that spectrum or width are not the correct type or value.
