I stand corrected and chastised.
By the way, I no longer consider Wikipedia a valid source of information.
That's why I emphasized that it is suitable only for fact-checking simple, uncontroversial statements.
Sometimes my memory needs jogging - "Is one parsec 3.26 light-years, or 3.25 light-years?" "Was 'Fat Man' a plutonium bomb, or a uranium bomb?" etc.) - and for that purpose, Wikipedia is adequate.
