Related catalog filenames
The files 89663-47052.bin and 89663-47052 (2).bin carry the same calibration identifier. The numbered suffix distinguishes the filenames, but it does not establish a different calibration, a modified variant or a particular software change.
For service identification, the complete identifier matters: a similar 89663 prefix alone does not establish that another calibration has the same application or function.
