anisotropic Gaussian blur test

[KKKc3231]

So amazing work!
I have a question that is not mentioned in the paper. Could you please tell me the details about the evaluation datasets under anisotropic Gaussian blur? In your paper, you have mentioned the evaluation datasets under isotropic Gaussian blur is Gaussian8，So, is the Gaussian8 process the Set5 to generate 40 images for evaluation during each iteration?, and how about the details of anisotropic Gaussian blur in evaluation.
Thank you a lot, looking forward to your reply.
Best wishes for you!
