K-Sigma Estimation

[zjysnow]

Hi, I have download the reno10x_noise dataset to estimate the k-sigma parameters, but I found that there are two folders have the same ISO=3938, is there anything wrong here?
Another question is that I found the E(x)-Var(x) curve is not always linear. When the luminance is higher, the curve is more non-linear, I want to known if I miss some pre-processing. Now I just read the raw data and minus the black level. Also I tried to use different strategy to sample the data and cannot achieve the result of yours, is there any trick here?

sorry, I found that the last image in group iso=3200 is iso=3938, I use the last data as x, so I got the wrong data

这个事因为最后一张图分错了，至少那个分类的最后一张图的info是错的
