Pous Index

The Pous index is one of the many quantitative tools used to evaluate the quality of a researcher's works.
It is defined as the length of the smallest author chain reaching Damien Pous for the copublication relation (very similar to the Erdös number , yet using Damien Pous instead of Paul Erdös).
A useful website for computing one's own Pous index, (as well as a great number of other indices).
The Pous Index is considered more accurate than the Habermehl Index, even if the latter is more universal, and can be used in other research fields.
