- Removed redundant functions for crossing direction and moon phase label names, replacing them with direct usage of enum values. - Updated output formatting in demo and example files to utilize operator overloads for cleaner code. - Introduced stream operators for various classes including AzimuthExtremumKind, Position, Geodetic, Direction, and lunar phase enums for improved output readability. - Enhanced Target class to support strongly-typed celestial directions, ensuring automatic conversion to ICRS where necessary. - Added tests for new Target functionality, verifying altitude calculations and typed accessors for ICRSTarget and EclipticMeanJ2000Target. - Updated coordinate tests to use qtty::Degree for consistency and clarity in direction initialization.
- Adjusted formatting in test files to improve readability by aligning code and comments. - Replaced multiple lines of code with more concise versions in tests for TypedCoordinates, Ephemeris, Observatories, and Time. - Ensured consistent use of spacing and indentation across all test cases. - Verified that all assertions and static assertions maintain their intended functionality.
- Implemented body-centric coordinate transformations in `bodycentric_transforms.hpp`. - Introduced `BodycentricPos` template struct for handling body-centric positions. - Added `to_bodycentric` function to convert geocentric/heliocentric positions to body-centric coordinates. - Created `BodycentricParams` struct to encapsulate orbital parameters and reference centers. - Added Mars heliocentric position calculation in `ephemeris.hpp`. - Developed a new example `l2_satellite_mars_example.cpp` demonstrating Mars's position as seen from a JWST-like L2 orbit. - Enhanced `Position` class in `cartesian.hpp` with distance calculation methods. - Added unit tests in `test_bodycentric.cpp` to validate body-centric transformations and Keplerian position calculations.
…ses, and trackable targets - Implemented `17_serde_serialization.cpp` to demonstrate manual JSON serialization for siderust types. - Added `18_kepler_orbit.cpp` to showcase Keplerian orbit propagation with a manual solver. - Created `19_brent_root_finding.cpp` to illustrate a manual implementation of Brent's root-finding method. - Developed `20_moon_phase.cpp` to demonstrate lunar phase calculations and event searches. - Introduced `21_trackable_demo.cpp` to showcase polymorphism in handling various astronomical targets. Updated headers to include new position conversion methods between Cartesian and spherical coordinates.

…sformation functionalities - Deleted several example files including bodycentric_coordinates.cpp, coordinate_systems_example.cpp, coordinates_examples.cpp, demo.cpp, l2_satellite_mars_example.cpp, solar_system_bodies_example.cpp, and trackable_targets_example.cpp to streamline the codebase. - Added a new function `in_azimuth_range` to find periods when a star's azimuth is within a specified range. - Introduced new methods in the `Position` class for transforming positions to different reference centers and combined frame + center transformations. - Added a new type alias `HCRS` for Heliocentric positions in the equatorial frame. - Implemented a new function `mars_barycentric` to retrieve Mars's barycentric position using VSOP87. - Updated submodules for qtty-cpp, siderust, and tempoch-cpp to their latest commits.
…ality - Converted Rust serialization examples to C++ in `11_serde_serialization.cpp`, demonstrating manual JSON-like serialization for time, coordinate, body-related, and target objects. - Added file I/O capabilities to save and load serialized data. - Introduced new functions in `ephemeris.hpp` for calculating heliocentric and barycentric positions of Mercury, Venus, Jupiter, Saturn, Uranus, and Neptune using VSOP87. - Expanded time-related types in `time.hpp` to include TDB, TT, TAI, TCG, TCB, GPS, UT, UniversalTime, JDE, and UnixTime. - Updated submodules for siderust and tempoch-cpp to the latest commits.
- Introduced a unified Subject type to represent any celestial entity, allowing for simplified function calls for altitude, azimuth, and other calculations. - Updated existing celestial body and star references to use the new Subject API. - Added tests for the Subject API covering various celestial entities including bodies, stars, and ICRS directions. - Refactored existing tests to accommodate changes in how celestial bodies and stars are accessed. - Updated CMakeLists.txt to include the new test file for Subject.
