Reading the catalog identifiers
The 30D41 and 30E-series entries identify distinct calibrations. Their similar numbering does not establish that they are interchangeable or that one supersedes another. The combined catalog string also includes suffixes such as -A, but it does not explain whether those suffixes denote a stock file, a modified variant or another catalog distinction.
