Full counting statistics of a voltage-driven normal metal-superconductor contact.

For a bias voltage below the superconducting gap the contact NS can be mapped onto an NN-contact with doubled voltage and counting fields.

In the Andreev regime the transport characteristics can be obtained from the normal metal results.

The elementary processes are single and electron- and hole-like Andreev transfers.

Optimal quantization is obtained for half-integer Levitons.
