    It is not clear to me what the 34digit field means. Is it to adjust accuracy?

    Purpose of use
    Understand Poisson parameter roughly. Estimate if given problem is indeed approximately Poisson-distributed.
    Comment/Request
    I was expecting not only chart visualization but a numeric table. The FAQ may solve this. However my problem appears to be not Poisson but some relative of it, with a random parameterization. I fear the characterization might be above my pay grade. Some similarity to Zipf distribution is possible .. in Zipf, each entry n = 1,2,3.. has frequency f(n) and log(n) is reversely proportional to log(f(n)) -- approximately.
