Version 4.4

Added method to calculate the angular separation between two equatorial coordinates.

Version 4.3

• Added methods to calculate the refraction for given horizontal coordinates.

Version 4.2

• Added view with the length of the night at a given location.
  

Version 4.1

• Added view with the altitude of the target during the night.
  

Version 4.0.1

• Corrected convertToDegrees method on Coordinates to return h m s, instead of h ' ".
• Added getCoordinates method on Target.

Version 4.0

Changed

• Removed abstract Coordinates class.
• Added Coordinate class and reworked all Coordinate Classes to use this new class.

Added

• Added classes for Targets, Moon, Sun, and Planet.
• Calculation of rising, transit and setting for targets.
• Calculation of best time to observe a target.
• Calculation of highest altitude of a target.

Version 3.1

Added

• Calculation of parallactic angle.

Version 3.0

Changed

• GeographicalCoordinates class now inherits from the abstract Coordinates class.
• Moved GeographicalCoordinates to deepskylog\AstronomyLibrary\Coordinates.
• The method apparentSiderialTime of the Time class can take an extra parameter nutation.

Added

• Added abstract Coordinates class.
• Added EquatorialCoordinates, EclipticalCoordinates, Horizontal and GalacticCoordinates classes.
• Added conversion between the Coordinates classes.

Version 2.0.1

Since laravel-astronomy-library 2.0, the minimal required version of php is 7.4. This means that also laravel 7.0 is needed.

Version 2.0

Changed

• The constructor of AstronomyLibrary now needs the geographical coordinates as parameter.

Added

• Added methods to calculate the dynamical time.
• Added methods to calculate the mean and apparent siderial time at the given location.
• Added methods to calculate the nutation for a given date.
• Added GeographicalCoordinates class.
