The photospheric and CI chondrite abundances (P and CI, respectively) show a strong correlation. CI as a proxy is also justified by the (i) smoothness of their abundances plotted as a function of odd mass number and (ii) agreement within the error of P as determined spectroscopically. But our statistical assessment of spectroscopic studies and solar wind from the Genesis mission indicates that the small, ~10%\u201330%, differences (residuals) between CI and P depend on the 50% condensation temperature (Tc50). So, if CI is to be used as a proxy for P, Cosmochemists may want to add a correction to individual elements. Our work is consistent with two published hypotheses: that (i) residuals are linear with Tc50 and (ii) that elements having Tc50\u2009>\u20091343\u2009K are depleted relative to those with 495\u2009K\u2009&lt;\u2009Tc50\u2009&lt;\u20091343\u2009K in CI. We discuss other interpretations which are also feasible. Understanding these small differences of the CI and P for different elements and their variation with Tc50 can help constrain future models of solar system formation and the history of CI chondrites.&#8221;<\/p>\n\n\n\n<p><strong>Update (11 November 2025) : <\/strong><\/p>\n\n\n\n<p><strong>Correction to Differences in Elemental Abundances Between CI Chondrites and the Solar Photosphere<\/strong><\/p>\n\n\n\n<p>MAPS, Version of Record online: 10 November 2025<\/p>\n\n\n\n<p><a href=\"https:\/\/onlinelibrary.wiley.com\/doi\/10.1111\/maps.70059\" target=\"_blank\" rel=\"noreferrer noopener\"><strong>LINK (OPEN ACCESS)<\/strong><\/a><\/p>\n\n\n\n<p>&#8220;Jurewicz, A.
