Catalog variants
The files 89663-30C02.bin and 89663-30C02 (2).bin carry no modification label. The (2) suffix distinguishes a filename but does not establish a different calibration.
The filenames 89663-30C02-_MOD.bin, 89663-30C02-_MOD_E2.bin and SW#89663-30C02- MOD_E2.bin identify modified-labeled variants. The two MOD_E2 names also carry an E2 label, but the filename alone does not establish what that label changes or whether the files are identical.
