Hi all!
I recently came across this problem where I am measuring 176Lu/177Hf, and the counts for 177Hf are very low, sometimes zero, which leads to ratios getting really big. the masking option doesn't help me here is i can only mask input channels, not the intermediate ratio. When I'm fitting a spline through the data (Spline_AutoSmooth) it fits a straight line through the data rather than a smooth spline leading to very large (and unnecessary) uncertainties. Does anybody know how to mask ratios that approach infinity? I know I can flip it around and calculate an inverse isochron but that's not what i'm after here.
Cheers, kai
