[seqfan] Definition of A002190

[Paul D Hanna]

Seqfans,  
      The definition of A002190 is: 
Sum_{n>=0} a(n)*x^n/n!^2 = -ln(BesselJ(0,2*sqrt(x))).  
[1, 4, 33, 456, 9460, 274800, 10643745, 530052880, 32995478376, 2510382661920, ...]
(OFFSET 2). 
  
However, by the definition the offset should be 1 and a(1) = 1, since
-log( Sum_{n>=0} (-x)^n/n!^2 ) = x + x^2/2!^2 + 4*x^3/3!^2 + 33*x^4/4!^2 + 456*x^5/5!^2 + 9460*x^6/6!^2 +...
 
The question is, should the sequence be changed to include a(1)=1, 
or should the definition be changed to fit the existing sequence, i.e., 
change the name to: 
   Sum_{n>=0} a(n)*x^n/n!^2 = -x-ln(BesselJ(0,2*sqrt(x))).  
 
I would vote for prepending a '1' to the existing sequence and changing OFFSET=1 to fit the definition, 
but I fear changing an old classic sequence without the consensus of SeqFans. 
 
Thanks, 
      Paul
