查看“Galaxy morphology”的源代码

==软件==

*astropy中的astropy.modeling.functional_models.Sersic2D
 ny, nx = 240, 240
 y, x = np.mgrid[0:ny, 0:nx]
 sersic_model = models.Sersic2D(
    amplitude=1, r_eff=20, n=2.5, x_0=120.5, y_0=96.5,
    ellip=0.5, theta=-0.5)
 image = sersic_model(x, y)

*photoutils中的测光
 from photutils import EllipticalAperture, EllipticalAnnulus
 from photutils import aperture_photometry
===statmorph===
*[https://statmorph.readthedocs.io/]
:基本的形态参数测量，如CAS，MID，Gini-M20，还有单sersic轮廓拟合


===PyAutoGalaxy===
*可以生成星系的仿真图片
*也可以调用一个pyautofit来进行模型拟合
