Abstract
This short technical note addresses a number of issues regarding the estimates of the 2004 paper by Ericson, Loiseau, and Wycech for the corrections and , which aim at the removal of the effects of electromagnetic origin from the measurements of the strong-interaction shift and of the total decay width of the ground state in pionic hydrogen.
