Source levels
Main value = the modeled value (nominal, else the middle of min-max).
Grey under a value = its min-max, where the source gives both.
< / = = the source gives only that limit, modeled at it. ref = reference.
L2 = the standard itself (or its complete free preview, or the maker's drawing).
View fro! L1 = two or more independent sources agree: the release gate. LO = one source only: printed amber and marked *. c = a source value was corrected; the datasheet says how.
House convention = a detail no source dimensions, drawn to a stated house rule. This size's values: L2 15 - L16.
Notes
s: modeled at the middle of its band; e and kw are checks, not modeled.
