PDF positivity

These pseudo-observables can be used to enforce the positivity of PDFs in a PDF fit [CFGH23, CFH20, CRS22]. This is a built-in interface.

Pinecard structure

The positivity.yaml file (compulsory). This file contains the PID and kinematics of the pseudo-observable.

Additional metadata

No additional metadata is written.

Output

No additional output files are created.
