Superbias: Columns Or Rows or Both

[Farzad_k]

Hi,

I know it should be obvious that if it looks like the master Bias has vertical lines you should use Columns when doing Superbias and it implies then that you use Rows if the master Bias has horizontal lines? Is there a time when both can be used? How eill two Super Biases be applied to calibrate data?

Thanks
