h2-center index

The h-index describes an h×h square under the citation curve containing h2 citations. Bornmann et al. (2010) suggest dividing the citation curve into three sections based on this square and describing each section as the percent of all citations found within the section.

The h2-center index is the percent of citations found within the h-square. It is calculated as:$$h_\text{center}^2=\frac{h^2}{C^P}\times 100$$
