NAC images acquired on consecutive orbits, or occasionally over non-consecutive orbits under very similar lighting conditions (e.g. less than 5° difference in incidence angle and the same sun direction), can be combined to create controlled mosaics. A control network is generated to tie the images to the most accurate ground truth available and a bundle adjustment is performed to correct for pointing errors and image alignment. The images are then map-projected and mosaicked together into an almost seamless mosaic of the region. The digital terrain model used for the radius source and for map-projection are listed below. </p> <p> There are a few files included to assist in evaluating the controlled mosaic. These include:</p> <p> Bundleout.txt - The output text file from the ISIS3 jigsaw tool summarizing the results of bundle-adjusting the control network. For more information, see: <a href=https://isis.astrogeology.usgs.gov/Application/presentation/Tabbed/jigsaw/jigsaw.html>https://isis.astrogeology.usgs.gov/Application/presentation/Tabbed/jigsaw/jigsaw.html</a></p> <p> Residual Plot - A plot of every residual overplotted onto a 20 m/px version of the mosaic. This is useful for local inspection of residuals (in pixels), which ideally should be zero, but we consider residuals less than one acceptable.</p> <p> Binned Residual Plot - A plot with the residuals (in pixels) binned by 0.05 degrees of latitude and longitude. It can be used to determine if there are any trends in the residuals over the entire mosaic. Ideally residuals should be very close to zero and there should be no trends in the directions.</p> <p> In addition to the provided files, we have included the Sigma0 value below, which is the standard deviation of unit weight and a summary number for the bundle-adjustment performed by jigsaw. Ideally, Sigma0 should be less than one. </p> </p><p> <p> When citing this product, use the following reference:</p> <p>Klem, S. M., Henriksen, M. R., Stopar, J., Boyd, A., & Robinson, M. S. (2014).
