v1.5.1

[attipaci]

Bug fix release.

Fixed

• novas_print_dms() incorrect string representation of negative angles. #270: novas_print_dms() gave incorrect representations of negative angles, whereby the negative sign was repeated in the minutes and seconds components also.

• CMake / vcpkg configuring issue #272: CMakeLists.txt exported the core target by another name of supernovas, which messed up the CMake package dependencies and also vcpkg. Fixed by not renaming core target.

• novas_sep - error in haversine formula #275: Error in novas_sep() formula. (thanks to @prookyon)

• Fixes and improvements to Moon's orbital modeling #276: Wrong eccentricity value in novas_make_moon_orbit(), resulting in errors up to a few degrees in the Moon's orbital modeling. (thanks to @prookyon)

Changed

• Export core target without re-naming #273: Removed CLEAN_DIRECT_OUTPUT from CMakeLists.txt. It's an option that is no longer needed or used (since 2009).

• Export core target without re-naming #273: Removed unnecessary POSITION_INDEPENDENT_CODE from CMakeLists.txt. (It's automatic for shared libraries.)

• Export core target without re-naming #273: Updated README.md CMake snippet for building against the supernovas package.

• Fixes and improvements to Moon's orbital modeling #276, More tweaks to Moon orbital model. #280: Improved Lunar orbital modeling in novas_make_moon_orbit(), by using the leading terms from the ELP/MPP02 model, for a typical accuracy at the 10 arcmin level for a day or so around the reference epoch of the orbital parameters.

• strcpy() -> strncpy() #284: Changed strcpy() calls to the safer strncpy(). (thanks to @ChooseAfferoGPL)

• novas_sep() now uses the Vincenty formula for calculating distances on a sphere, which is accurate for all locations, unlike the law of cosines or the haversine formula used previously.

• CMake: cmake_minimum_required() now includes current version upper bound of 4.2, in preparation to CMake 4.0 (see https://fedoraproject.org/wiki/Changes/CMake4.0 for more explanation).

• Fix unclosed code blocks in Doxygen markup (causes errors in latest Doxygen).

• CMake libraries (targets) built with transitive dependencies.
