Owing to unfortunate figure reproduction issues, the figures for the printed and on-line editions of the article “In-situ Measurements of Temperature Distributions in a Microwave-Heated Cavity” by Finegan et al. (Volume 52, No. 8, August 2006, pp. 2727–2735, DOI: 10.1002/aic.10897) did not reflect the quality of the originally-submitted artwork, and many of the features crucial to the interpretation and discussion of the results were not discernable. These figures are reproduced here in their original quality to enable correct visualization of the experimental and predicted temperature distributions in a microwave heated cavity. 1, 2, 3, 4, 5, 6, 7, 8, 9
