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

Note: The data for this variable from file A was filtered.
Note: The data for this variable from file B was filtered.
Note: The latitude in file A was filtered.
Note: The longitude in file A was filtered.
Please see the original configuration file to view any data filtering functions.

latitude in A: Latitude
latitude in B: pixel_latitude
longitude in A: Longitude
longitude in B: pixel_longitude
longitude/latitude comparison epsilon: 0.0

WARNING: 15501264 data points (86.12% 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.
