在Astropy中，计算两个天体在球面上的角距离可以使用`astropy.coordinates.angle_utilities.angular_separation`函数。这个函数可以计算两个天体在三维球面上的角距离（也称作差分角距离）。 以下是一个示例代码，展示如何使用`angular_separation`函数计算两个天体在球面上的角距离： fromastropy.coordinatesimport...
This pull request addresses the feature request in Issue#1012: Add option to project separation onto an ellipse. The changes implement the ability to compute separations not just as an angular distance between two coordinates but also along a specified elliptical axis, which is particularly useful i...
The AngularSeparation class has been removed. The output of the coordinates separation() method is now an astropy.coordinates.Angle. [#1007] The coordinate classes have been renamed in a way that remove the Coordinates at the end of the class names. E.g., ICRSCoordinates from previous versio...

astropy.coordinates Frame attributes set on SkyCoord are now always validated, and any ndarray-like operation (like slicing) will also be done on those. [#5751] Caching of all possible frame attributes was implemented. This greatly speeds up many SkyCoord operations. [#5703, #5751] A class ...
astropy.coordinates Computing a 3D separation between two SkyCoord objects (with the separation_3d method) now works with or without velocity data attached to the objects. [#7387] astropy.io.votable Fix validate with xmllint=True. [#7255, #7283] astropy.modeling FittingWithOutlierRemoval now...
