Dataset

Description

The dataset is made of three different files:

- Perrin-et-al-Calculated-DEMs.zip : we use HiRISE stereo pair images (https://www.uahirise.org/) to compute high-resolution DEMs along the Cerberus Fossae system using the SOCET SET mapping software (©BAE Systems). The stereo images are selected at different locations on the fossae in order to get an overall view of the lateral variation of the morphology along the Cerberus Fossae system. Stereo pairs were identified through ISIS image processing software package (USGS). They are calibrated based on the HiRISE camera specifications, corrected from jitter effects by the USGS ISIS software and then implemented into SOCET SET. Bundle adjustment is made in an absolute reference frame defined by MOLA. The coarser first iteration of DEM calculation is seeded on the gridded MOLA elevations at a resolution of 2 m/pixel. It is then followed by a refined DEM computation at higher resolution (up to 1 m/pixel). Post-processing DEM corrections are performed on outlying points to discard aberrant calculations.

- Perrin-et-al-SegmentationFig4.xlsx: list of the segment names and lengths that have been identified along Cerberus Fossae, Mars.

- Perrin-et-al-Width-Throw-Fig9.xlsx: measurements of widths and throws performed along Cerberus Fossae (Graben 1). Throw measurements are from Vetterlein and Roberts 2010 (MOLA data). Width measurements have been done using CTX images. Wa, Wt and Wb are respectively apparent widths, and widths measured at the top and the bottom of inferred fault scarps (i.e., steepest slopes).
