基本范例  (3)

绘制以北极星为中心的天空图：

Wolfram Language code: AstroGraphics[AstroCenter -> Entity["Star", "Polaris"], AstroRange -> Quantity[20, "AngularDegrees"]]

显示当前你所在地北方的天空图：

Wolfram Language code: AstroGraphics[AstroCenter -> "North", AstroRange -> Quantity[30, "AngularDegrees"]]

显示给定日期木星周围的伽利略卫星：

Wolfram Language code: AstroGraphics[AstroCenter -> Entity["Planet", "Jupiter"], AstroRange -> Quantity[0.2, "AngularDegrees"], AstroReferenceFrame -> {"Ecliptic", DateObject[{2022, 10, 22}]}]//QuietEcho

范围  (4)

用天文实体指定 AstroCenter 的值：

Wolfram Language code: AstroGraphics[AstroCenter -> Entity["Star", "Betelgeuse"], AstroRange -> Quantity[20, "AngularDegrees"], AstroReferenceFrame -> "Equatorial"]

用字符串指定 AstroCenter 的值：

Wolfram Language code: AstroGraphics[AstroCenter -> "TrueEquinox", AstroRange -> Quantity[15, "AngularDegrees"]]

用以 AstroPosition 给出的明确坐标指定 AstroCenter 的值：

Wolfram Language code: AstroGraphics[AstroCenter -> AstroPosition[{0, 0}, "Galactic"], AstroRange -> Quantity[15, "AngularDegrees"], AstroBackground -> "GalacticSky", AstroReferenceFrame -> "Equatorial"]

在参考框架的默认球坐标中使用明确的 {lon,lat} 坐标：

Wolfram Language code: AstroGraphics[AstroCenter -> {100, 10}, AstroRange -> Quantity[20, "AngularDegrees"], AstroReferenceFrame -> "Equatorial"]

这相当于明确使用相同的参考架：

Wolfram Language code: AstroGraphics[AstroCenter -> AstroPosition[{100, 10}, "Equatorial"], AstroRange -> Quantity[20, "AngularDegrees"], AstroReferenceFrame -> "Equatorial"]

应用  (1)

可视化日出附近的天空，太阳的上沿正好触及地平线：

Wolfram Language code: AstroGraphics[AstroCenter -> Entity["Star", "Sun"], AstroReferenceFrame -> {"Horizon", Sunrise[]}, AstroRange -> Quantity[2, "AngularDegrees"]]

属性和关系  (1)

AstroGraphics[AstroCentercenter,AstroRangeradius] 等价于 AstroGraphics[center,AstroRangeradius]：

Wolfram Language code: AstroGraphics[AstroCenter -> Entity["PlanetaryMoon", "Moon"], AstroRange -> Quantity[5, "AngularDegrees"]]
Wolfram Language code: AstroGraphics[Entity["PlanetaryMoon", "Moon"], AstroRange -> Quantity[5, "AngularDegrees"]]

互动范例  (1)

动态控制 AstroGraphics 图的中心：

Wolfram Language code: Manipulate[AstroGraphics[AstroCenter -> AstroPosition[{ra, dec}, "Equatorial"], AstroRange -> Quantity[30, "AngularDegrees"], AstroReferenceFrame -> "Equatorial", ImageSize -> Medium]//QuietEcho, {ra, 0, 360}, {{dec, 0}, -90, 90}, SynchronousUpdating -> False]
