OMEGA-Py - v3.2

OMEGA-Py v3.2 – Updates

From the release of version 3.0, OMEGA-Py has been officially validated by the OMEGA team and is distributed as an official OMEGA software alternative to the IDL version. https://www.ias.u-psud.fr/omega/software.html

A complete online documentation has been written and is available at https://astcherbinine.github.io/omegapy/

omega_data

• Add additional geometry planes in OMEGAdata:
  • dist: slant distance from spacecraft to the center of the pixel [km]
  • phase_n: phase angle w.r.t. the local normal
• Add L-channel geometry
• Fix issue when loading Phobos observations, where the spacecraft orientation is not provided in the header

omega_plots

• Enable use of L-channel geometry in display functions with use_L_geom

OMEGA-Py v3.0 - Official – Major updates

From the release of version 3.0, OMEGA-Py has been officially validated by the OMEGA team and is distributed as an official OMEGA software alternative to the IDL version.

A complete online documentation has been written and is available at https://astcherbinine.github.io/omegapy/

Updates to the omega_data.OMEGAdata class

• Improve binaries processing to have a perfect match with the IDL version of the code, force the use of float32 instead of float64
• Add focal plane and spectrometer temperatures for all channels
• Add incidence and emergence angles w.r.t. the local normal (in addition to the ellipsoid)
• Add omega.ref_C, surface reflectance map to be compared with cos(inci_n) to check the geometry spatial calibration
• Add geometry information for the V-channel (which is slightly different to the one of the V+L channels)
• Add distance to Sun in km (in addition to a.u. value)

omega_plots

• Add option to use the V-channel geometry in all the display functions that use projection (use_V_geom=True)

omega_data

• Add option to filter only the data cubes acquired with nadir geometry in find_cube (nadir_only=True)

OMEGA-Py - v2.4

OMEGA-Py v2.4 - Updates

omega_data

• Add omega_mask function to generate masks used in the omega_plots functions.

omega_plots

• Add new projection method for composite maps: proj_method=2 accounts for the entire footprint of each pixel to create high-resolution maps. But it takes much more time to process.

OMEGA-Py - v2.3

OMEGA-Py v2.3 - Updates

Fixes several issues related to the use of the module with Windows.

omega_data

• Fix compatibility issues with Windows for the importation and correction of OMEGAdata objects.
• Disable the use of multiprocessing for thermal correction with Windows.
• Fix definition of custom paths for binary and python files with set_omega_bin_path() and set_omega_py_path().

omega_plots

• Add the mask argument in show_omega().
• Fix gaps between pixels in composite maps.

OMEGA-Py - v2.2

OMEGA-Py v2.2 - Updates

Update script functions from SOFT09 to SOFT10: extent the L-channel correction up to orbit 13131 (see the SOFT10 README for more details).

omega_data

• Add the get_header_qub and get_header_nav methods to the OMEGAdata class
• Change average datetime to median datetime (OMEGAdata and find_cube) to fix issue with partially corrupted geometry informations

omega_plots

• Add the **kwargs argument *v2 plots functions. Pass additional parameters of the plt.colormesh function for the plot.
