Size of u_img & raw data

[KWang1998]

I've run psf_pipeline_only.m. But I found u_img in the "..._bayer.mat" used in this model is 2976x3968 double. However, I found in pipeline_bayer.m, u_img is saved as ( : , : , 5). So, are these "..._uimgs_bimgs_bayer.mat" use only one type of noise instead of 5?

Besides, if it's convenient for you, could you please upload your raw data of the images taken with phone? Thanks a lot~
