Still, the determination of the cosmic-ray ionisation rate of H$_2$ (${\\zeta^{\\rm ion}_{{\\rm H}_2}}$) is plagued by uncertainties in the adopted chemical networks and the analysis techniques. This work aims to homogeneously estimate the ${\\zeta^{\\rm ion}_{{\\rm H}_2}}$ at parsec scales towards the Orion Molecular Clouds OMC-2 and OMC-3, probing its variation across a whole star-forming region and a range of column densities never explored before.
