Dear Ilya,

Sorry, my mistake. Indeed, the exponential decrease would be
[[1],3/2]. But a decrease in x^(-3/2) or x^(-2) is an ordinary
slow decrease, so I maintain that one should use [[1],0], or
equivalently simply [1]. I must admit that I do not remember what
[[1],-3/2] would mean, but certainly not X^(-3/2), so on that point
the doc is wrong. Perhaps "very slowly decreasing like X^(-z)"
in the doc should be replaced by "very slowly decreasing like
1/(X\log(X)^z)", but I am not sure, need to be checked.
