wfirst_simulation 对于主要模拟,请使用wfirst_simple_sim.py(包括多个参数;星系数,星系模型,PSF模型,剪切测量方法。固定参数为; random_seed = 314,dither = 22535,SCA = 1,filter = H158,stamp_size = 32 ,hlr = 1.0)主要仿真以拟合格式返回ngmix输出或metacalibration输出(noshear,1p,1m,2p,2m)。 要使用wfirst_simple_sim.py,请使用“ python wfirst_simple_sim.py galaxy_number galaxy_profile psf_profile shape_measurement”(例如python wfirst_simple_sim.py 3000000'Gaussian''Gaussian
