Any combination of these modules can be created without changing anything to the standard Transfer module (TM) and Rod Maker module (RMM).

The calculation can be performed with standard transfer matrix technique computer programs. The procedure provided here can avoid the calculation difficulty met in the procedure of some literatures.

The current methods of the radiometric calibration are based on the establishment of high-precision primary standard and standard transfer chain, and the transfer chain is the main source of errors.
