TL;DR

This paper identifies and corrects two errors in a previous study on antiproton production cross sections, improving the accuracy of data used in cosmic ray research.

Contribution

It provides corrected parameter values and units for the antiproton production cross section, addressing errors in a prior influential publication.

Findings

Corrected fit parameter value for antiproton production

Adjusted units for cross section data

Enhanced accuracy for cosmic ray studies

Abstract

The referred-to paper on antiproton production contains two errors: an error in the value reported for one of the fit parameters and an error in units. I give the errors and the corrected values when possible.
