Data used in the analysis of Baltis Vallis, Venus

The files included in this data repository were used in the analysis and figures of Conrad and Nimmo (2023) to determine the characteristic wavelengths of the Baltis Vallis canale.

Baltis Vallis is a ~7000 km long channel on the surface of Venus that was altered over most of that length.

The included files are in comma separated values format with the first line giving the column descriptions.

File Descriptions:
FordVenus720shape.txt = Spherical Harmonics Coefficients derived from Ford and Pettengill (1992)'s topography
BaltisVallis_LLT.csv = Baltis Vallis longitude, latitude, topography sampled from ArcGIS
BaltisVallis_Metrics_North.txt = % downhill and conformity factor as a function of maximum spherical harmonic degree. North source case
BaltisVallis_Metrics_South.txt = % downhill and conformity factor as a function of maximum spherical harmonic degree. South source case
Synthetic_Metric_Deviation.txt = Standard deviation of % downhill and conformity factor for our 1000 synthetic profiles.
BaltisVallis_Power_Spectrum.txt = Topographic power spectra of the topography presented in BaltisVallis_LLT.csv

BV_Synthetic_Gen.py = generates the synthetic topographic spherical harmonic coefficients

BV_Topo_Conf.py and Venus_Synthetic_Topo_Conf.py = determines metric values for Baltis Vallis and synthetic Baltis Valli respectively.

BV_TopoPower.py = from the BaltisVallis_LLT.csv file calculate the topographic power spectra and plot it.
