AtlasPID: bugfixes for isBBbarMeson and isCCbarMeson methods
Previously the isCCbarMeson
method was returning false for J/Psi (pdg_id=443) and all other ccbar mesons. isBBbarMeson
had the same bug, but in addition was returning the values for isCCbarMeson
by mistake.
Bug was introduced in !69440 (merged) (25.0.1 onwards).
