Version 4.12.2

New Datasets!

  • Added new ultra-high degree shape models of the Moon in both principal axis and mean Earth/polar axis coordinate systems (LOLA_shape and LOLA_shape_pa) and moved MoonTopo2600p to historical.
  • Added new ultra-high degree shape model of Mars (MOLA_shape) and moved MarsTopo2600 and MarsTopo719 to historical.
  • Added a new ultra-high degree shape model of Mercury based on the USGS SPG DTM (USGS_SPG_shape).
  • Added a new ultra-high degree shape model of Vesta based on the DLR SPG DTM (DLR_SPG_shape).
  • Added a new ultra-high degree shape model of Ceres based on the DLR SPG DTM (DLR_SPG_shape) and a high-degree shape model based on the JPL SPC DTM (JPL_SPG_shape).
  • Added historical degree-2 gravity models of Io, Europa, Ganymede, and Callisto derived from data collected by the Galileo mission.
  • Added two shape models of Titan (Mitri2014_shape and Corlies2017_shape) and a degree 5 gravity model of Durante et al. 2019 (Durante2019_gravity).
  • Added two gravity models of Enceladus (Iess2014_gravity and Park2024_gravity) and a high-degree shape model based on the JPL SPC DTM (JPL_SPG_shape).
  • Added two shape models of Eros (NLR_shape and SPC_shape) and the JPL gravity model JGE15A01.
  • Updated all constants to reflect the most recent datasets, and added new constant modules for Eros, Io, Europa, Ganymede, Callisto, Titan and Enceladus.
  • Added the property volume_equivalent_radius and volume to the constants modules.
  • Renamed the constant attributes density to mean_density and g0 to gravity_mean_radius.
  • Updated all datasets that download from zenodo to use the Pooch DOIDownloader.

Bug fixes

  • When importing an xarray grid with SHGrid.from_xarray(), check if the first row is 90 or -90 and flip accordingly.
  • Fixed a bug in SHCoeffs.convert() when coefficient errors are present.
  • Fixed a bug in spectralanalysis.cross_spectrum() when using real unnormalized coefficients.

Plotting improvements

  • Added the optional parameter rectangle to the SHGrid.plotgmt() method that allows the use of rectangular projections that are specified by the lower-left and upper-right coordinates.
  • Added the optional parameter cmap_background_foreground to SHGrid.plotgmt() that controls how data are plotted when they exceed the limits of the colormap.
  • Added the optional parameter title_offset to SHGrid.plotgmt() and SHGrid.plot() that specifies how much space to add between the plot and title.
  • Cleaned up the SHGrid.plotgmt() shading options based on changes made in pygmt 0.7, including the use of xarrays directly instead of creating temporary files.
  • Added the optional argument cmap_rlimits and cmap_rlimits_complex to SHGrid.plot(), SHGrid.plotgmt() and SHGrid.plot3d() to specify colorbar limits with respect to the maximum value of the data.
  • Added the optional argument cmap_scale to SHGrid.plot() and SHGrid.plotgmt() to allow using either a linear or logarithmic color map.
  • Add the optional argument cb_power to SHGrid.plotgmt() to allow plotting annotations as powers of 10.
  • Added an option to SHCoeffs.plot_spectrum() to plot the error spectrum (if present) or not.

Other changes

  • Added "ifx" to the list of possible Fortran compilers in the Makefile.
  • Added the optional argument r to SHMagCoeffs.expand() and SHGravCoeffs.expand() that allows one to compute the field at an arbitrary list of (r, lat, lon) points.
  • Allow the passing of pathlib.Path objects to all methods that require a filename.
  • Added jupyter-core as a build dependency in pyproject.toml.
  • Changed the behaviour of the fortan function MakeCircleCoord when the angular radius is zero.
