Experimental data supporting the claim that a carbonaceous sulfur hydride (CSH) under pressure is a high temperature superconductor were presented. Here we report results of a mathematical analysis that indicates that with probability larger than 1-10 some of those data were not measured in a laboratory, contrary to what the papers claim. This finding undermines confidence in the claim that of the experimental evidence reported in those papers reflects the properties of real physical samples of CSH.
