No you use the histogram for the wideband you have.
o2s are more accurate than widebands so its always best to use them as much as you can.
If your wideband reads accurately down low which most down you should be able to compare it to the narrowbands and it should match so the error should be calculated the same but thats not always the case.
What did I do? Help a greenhorn out?
