v2.0.0

What's Changed

• Continuous integration: Migrated to GitHub actions
• Installation: Perl extension disabled by default (--disable-perl argument removed from configure). To enable perl extension, use --enable-perl
• IGRF: Updated to DGRF12/IGRF13. Update extrapolation to use secular variation.
• Lgm_QinDenton: Extra checks in Lgm_QinDenton to reduce unnecessary output and check for inputs with standard QD naming convention ([1min, 5min, hour], in that priority order)
• New functions: Lgm_Terminator, FluxTubeVolume, Lgm_ReplaceSubString2, Lgm_B_FromScatteredData6 added to library
• Experimental Gaussian Process Regression functionality added to library (not compiled in by default)
• Updates to enable second-order evaluation of fist adiabatic invariant
• magstep: Bulirsch-Stoer relative tolerance set to zero by default (only use absolute error)
• Updates to improve robustness of Bmin finding
• API change: Add RelaxTolerance argument to FindShellLine
• API change: Add ErrorStatus to all function variants of ComputeI_FromMltMlat
• TA16: Tsyganenko-Andreeva 2016 model added. Currently requires TA coeficient input files.
• TS04: Trap added for clean return if evaluating deep inside Earth
• JensonCain1960: New internal field model added
• Bug fixes: Correct altitude for lambda integrand in L* calculation, Correct angle in Lgm_EarthEclipse, Correct intersection calculation for Lgm_Ellipse
• Other: Preliminary version of field-aligned (PQB) coordinates, expanded KdTree functionality, updates to various examples, tests updated for expected changes, numerous minor documentation updates, etc.
• Code cleanup for LLVM compilers

v1.5.16

LANLGeoMag version 1.5.16 is a minor update and is considered stable. The new version includes bug fixes (including fixes for a smoother clean install), continuous integration with Travis and an expanded test suite, updates to handling of Shabansky orbits in the L* calculations, etc.

LANLGeoMag v.1.5.15-alpha

New tag to capture pre-release of updates, bug fixes and new functionality over last couple of years.
