What the filename identifies
The suffix _AVT_Stage1_E2 labels this file as a variant of the related 89663-06F51 catalog entry. “Stage 1” suggests a modified calibration, but the filename does not establish its tuning changes or the meaning of “AVT” and “E2.” The related base identifier is not itself labeled as a Stage 1 variant.
