I measured a peak (supposed to be a Lorentz one) and figured out afterwards that my detector was slightly saturated. So the tip of the peak is just a line.
Is there a way to still fit this one? Something like fitting a single Lorentz over a data range where the "bad" part is missing? Would that work? And how can I do this?

Hi FloTor,

Maybe you can mask the data in the flat part of the peak, then fit the plot? (You can use the regional masking tool button.)



Here, the red points are masked ones.
