0.1.6 (04-22-2026)

Order of linear interpolation changed. Parameters are now interpolated in fo, and converted to Nm.

Added an EDP builder derived from PyIRTAM to build the bottomside F2 layer using B0 and B1.
Added a tutorial to generate SH EDP parameters.
Added pandas to the list of dependencies.
Added unit tests for the new spherical harmonics features.
Added spherical harmonics reconstruction features for IRI EDP parameters (foF2, hmF2, B0, B1, foEs, M3000(F2)).
Increased min python version to 3.10 (which is a requirement for some scipy functions).
Added a new capability to do the Apex coordinate transformation without ApexPy.
Added unit tests for Apex_library.
Corrected foEs interpolation method and updated test data and example figures.
Deprecated output_quartiles argument in read_ccir_ursi_coeff() and replaced it with output_deciles (functionality is unchanged).
Typos are fixed in the Es section.
Added new hmF1 derivation based on B0 parameter.

Added magnetic filed strength and orientation as an output for IGRF library.
Added altitude as an optional input to the IGRF function.
Updated the README to include more links and information.
Updated the documentation to include more citation information, correct the installation instructions, and improve the examples.
Added logger and fixed merge conflicts between @aburrell and @victoriyaforsythe develop branches
Added a function to calculate vertical TEC
New library edp_update is added that introduces a new approach for the F1 region modeling, where all fields are now continuous. This is important for the raytracing application.
The construction of the EDP in edp_update was modified to improve the reliability of the code.
Coverage status is added.
Tests are added for edp_update.
Regression tests are added for monthly_mean function.
Regression tests are added for single_location function.
Test data files are added.
Plots are refreshed in the Docs.

The order of interpolation was changed. Previously the EDPs were constructed for 2 levels of solar activity and then interpolated in between. This was changed to the interpolation between parameters and the construction of the EDP for the final result.
Changed E-region height from 120 km to 110 km.
Added a link in the docs to the journal publication.
Print statements were deleted or replaced with logging messages.
