Experimenting superbias

[danlr46]

I am PixInsight freshman. I am using a Fujifilm DSLR with X-Trans sensor.
To make master Bias I am following the tutorial by Kayron Mercieca. I cannot work on CFA since I am not be able to get back RGB from CFA, so I have tried the method on RGB bias shots.
I have integrated 100 images.
To get the super bias I have generated columns and rows together. What I get is the situation in the three figures (one per channel) you see here:

Do they look sound? or is there any problem?


Thanks in advance for the help
