Astropy的coordinates模块提供了强大的坐标转换功能。 以下是一个简单的示例,展示如何将赤道坐标转换为银河坐标。 fromastropyimportcoordinatesascoord importastropy.unitsasu # 创建一个赤道坐标对象 ra=10.684*u.deg# 右升角 dec=41.269*u.deg# 赤纬 equatorial_coords=coord.SkyCoord(ra=ra,dec=dec,frame='icrs...
假设我们有一个天体的赤经和赤纬坐标,想要将其转换为黄道坐标,我们可以这样做: from astropy.coordinates import SkyCoordimport astropy.units as u # 定义赤道坐标系下的天体位置coord_eq = SkyCoord(ra=10.684*u.deg, dec=41.268*u.deg, frame='icrs') # 转换为黄道坐标系coord_ecl = coord_eq.transform_...

The deprecated functions for pre-0.3 coordinate object names like ICRSCoordinates have been removed. [#2422] The rotation_matrix and angle_axis functions in astropy.coordinates.angles were made more numerically consistent and are now tested explicitly [#2619] astropy.cosmology Added z_at_value ...
