how to use two dimentional prior distribuction

[rhuang-astro]

Hi,
I have two question about the usage of the NWAY.

First: in Salvato et. al. 2018, author generated two dimentional prior distribuction (W2, W1-W2), how to forward such data to nway? In the manual, it onlly have one dimention demo.

2nd: Is it possible to generate two dimentional prior distribuction taken from two catalog, for example, I want to match XMM with WISE, using the flux of XMM and magnitude of WISE to generate the prior function. Or even using the hardness of XMM and the flux ratio of X/IR?

Best,
Rui
