Experimental desorption rates. This work: CO:Ar (blue triangles) at 1486.6 eV (Al Ka) and 1253.6 eV (Mg Ka); Dupuy et al. (2021): Measured at 600 eV (pink star), scaled at 1253.6 eV (pink triangle), scaled at 1486.6 eV (pink circle). Extrapolated rates from the CO X-ray absorption cross section (NIST) (dotted lines) scaled using the desorption rates of CO:Ar at 1486.6 eV (Al Ka). The stripe indicates the margin of error in the NIST data.
