Denominators with which Paschen A061039(3n)=A144454 and A061040(3n)=A147650 can be calculated. A144454=A028560(3n)/a(n), A147650=A017162(n+1)/a(n).
a(n)=(1/12)*{-85*(n mod 9)+107*[(n+1) mod 9]-61*[(n+2) mod 9]-13*[(n+3) mod 9]+35*[(n+4) mod 9]+11*[(n+5) mod 9]-13*[(n+6) mod 9]+35*[(n+7) mod 9]+83*[(n+8) mod 9]}, with n>=0 [From Paolo P. Lava (paoloplava(AT)gmail.com), Nov 11 2008]
