Examples of jsky.science.Wavelength

jsky.science.Wavelength
This class manages wavelengths and provides a means to easily track different units. Users can set a static default units and then retrieve a wavelength value (as double) by calling getValue().. or user can requests wavelengths in one of the following specific wavelengths: getValue( Wavelength.METER)
