Asymmetric or Symmetric EIC

Hi JF_Fortin 

I would use asymmetric when I just want to use an integer mass to extract a chrromatogram and the software allows for a small negative mass defect and a larger positive defect.  If I want to use the mass with decimal places, i.e. including the mass defect, then symmetrical extraction makes more sense to me.

Thank you Andy. I use EIC for quantitative purpose instead of using TIC. I think based on your response, asymmetric seems a logical choice.
