Data for: Did Martian valley networks substantially modify the landscape?

''AGG-RB-MJ-KW-RG-dataset'' contains the main dataset. The table is organized so that each row is a valley network entry. Columns include the valley name (if applicable), lat/long, network stream order, the fit parameters and their standard error, upper and lower confidence bounds, RMS, concavity index theta, and basin hydrology exponent c with upper and lower bounds.

''AGG-RB-MJ-KW-RG-Context'' contains the geological and geomorpohlogical context of each valley network. The table is organized so that each row is a valley network entry. Columns include the valley name (if applicable), lat/long, geological unit of incision, age of the terrain, Neukum timing of valley activity, concavity index and background concavity index (from Stepinski et al., 2004), and spatial relationships with other valleys.
