Professors Dexter and Chelsea collaborated for a year while they were on leave. After returning to their respective institutions, they co-authored a paper that was subsequently published. After the paper appeared in print, Professor Chelsea discovered a transcribing error in the raw data appearing in Table 1 of the paper. The decimal points had been omitted in one column, resulting in all numbers being a factor of ten too large (9.2 was reported as 92, etc.). Subsequent calculations, however, were not affected since they had been performed with the correct data. Professor Chelsea called Professor Dexter and told him she had written an erratum and was planning to submit it. He maintained that the erratum was a waste of journal space and an unnecessary embarrassment. The calculated results and the conclusions were unaffected by the error, and no one was going to use the raw data for anything else anyway. Professor Dexter refused to consider an erratum despite Professor Chelsea's continued concerns. What should Professor Chelsea do?
