Explainer File for Supplementary Material Associated with Golombek, M. P., N. H. Warner, V. Ganti, M. P. Lamb, T. J. Parker, R. L. Fergason, and R. Sullivan (2014), Small crater modification on Meridiani Planum and implications for erosion rates and climate change on Mars, J. Geophys. Res. Planets, 119, doi:10.1002/2014JE004658. There are three supplements: Supplement 1: Complete Catalog of Small Craters Imaged by the Opportunity rover on her traverse from Eagle to Endurance crater arranged by 1a) the order of exploration and 1b) alphabetical order. Supplement 2: Complete description of the Opportunity Rover Traverse from Eagle to Endurance Crater Supplement 3: Table of crater diameter (square root of 2 bins), number of craters, and age from incremental size-frequency distribution of class 1-6 craters in the catalog imaged by the Opportunity rover on Meridiani Planum (highlighted diameters show the bins used for making the resurfacing correction as described in the text)
