SphericalCircle

class astropy.visualization.wcsaxes.SphericalCircle(center, radius, resolution=100, vertex_unit=Unit('deg'), **kwargs)

基类：Polygon

创建表示球面圆的面片-即，由球体上中心坐标的特定角度内的所有点组成的圆。这里我们假设纬度从-90到+90。

当用户想在天体图像上添加一个圆形的补丁时，这个类是必需的，否则圆会被扭曲，因为经度的固定间隔对应于天空中不同的角度，这取决于纬度。

参数:

centerPYTHON：元组或数量 [:ref: 'angle']

它可以是两个的元组 Quantity 对象，或单个 Quantity 具有两个元素的数组或 SkyCoord 对象。

radius : Quantity [:ref: 'angle' ]数量 [:ref: 'angle']

圆的半径

resolution : int ，可选PYTHON：int，可选

组成圆的点数-增加这个值可以得到一个更平滑的圆。

vertex_unit ： Unit单位

应定义生成多边形的单位-这应该与转换（例如WCS转换）期望作为输入的单位相匹配。

笔记

其他关键字参数传递给 Polygon

参数:

xy : (N ，2) array(N, 2) array

closed : bool ，默认： True布尔，默认：PYTHON：TRUE

多边形是否闭合(即，具有相同的起点和终点)。
