Level 1B product filename containing the scene measurements used. With the reference to the level 1B product file and sweep ID, it is possible to identify unambiguously the scene measurement that has been used for the actual spectral calibration. The reference to all underlying files can also be identified, including the offset calibration file, the gain calibration file, the LOS calibration file, the instrument characterization data file, the processing parameter file and the validation file.
