| Description: The Bin_Width_Constant class is used inside a Bin_Width_Lookup class for those cases where the bin width is either not well known or unknown. It provides a way to specify a nominal constant width or indicate that there is no available information about the bin width. If the bin width is completely unknown, use the appropriate bin_width attribute for the spectral type (frequency, wavelength, wavenumber, or energy), and indicate that it is nil, with a reason of "unknown". When this class is used, a full explanation of the situation should be provided by the bin_width_desc attribute of the parent class. |
