*array_2d
:为图像数据定义的一类二维数组类，包含了pixelsize信息，并可以同时包含mask信息
 ima_2d = aa.Array2D.no_mask(values=Agemap[0],shape_native=Agemap[0].shape,pixel_scales=0.5)
 noise_2d = aa.Array2D.no_mask(values=vflux**0.5+0.01,shape_native=Agemap[0].shape,pixel_scales=0.5)
 psf_2d = ag.Kernel2D.from_gaussian(shape_native=(10, 10), sigma=1.5, pixel_scales=0.5)

*imaging
:基于array_2d生成的图像类，必须同时具有原始图像数据，和noisemap，同时psf信息可选
 imaging=ag.Imaging(image=ima_2d,noise_map=noise_2d,psf=psf_2d)
