1201.5476 (H. C. Spruit)
H. C. Spruit
Use of the Hirsch-index ($H$) as measure of an author's visibility in the
scientific literature has become popular as an alternative to a gross measure
like total citations (c). I show that, at least in astrophysics, $H$ correlates
tightly with overall citations. The mean relation is $H=0.5(\sqrt c+1)$.
Outliers are few and not too far from the mean, especially if `normalized' ADS
citations are used for $c$ and $H$. Whatever the theoretical reasoning behind
it, the Hirsch index in practice does not appear to measure something
significantly new.
