A configuration file was used to control the production report.
Please see this copy of the configuration file for details.

latitude in A: pixel_latitude

longitude in B: pixel_longitude

WARNING: 22 data points (0.00055% of all data) show possible mismatch in values stored in file a and file b longitude and latitude values. Depending on the degree of mismatch, some data value comparisons in this report may be distorted or spatially nonsensical. Please consider re-running this report and including an examination of your longitude and latitude variables with appropriate epsilons in order to analyze the significance of the difference.
