32-digit values of the first 65 recurrence coefficients for orthogonal polynomials relative to the weight function w(x)=x^a*exp(-x)*log(1+1/x) on [0,Inf], a=-1/2, are computed by a 2-component discretization method using the routine sr_explogalgm1half0inf(32,65), where dig=48 has to be entered when prompted by the routine. The value 48 of dig has been determined by the routine dig_algm1halfexplog(32,4,32). The software provided in this dataset allows generating any number N <= 65 of recurrence coefficients for any noninteger a > -1, as well as for different precisions.
