Using the Orange Software (Quasar), I am trying to obtain the height of a spectral peak, which I thought I could do by the amplitude of a fitted Gaussian.

However, when I fit a Gaussian to my data (which has been normalized between 0-1), it is outputting an amplitude far greater than 1 (16.9 in the attached figure). Does anyone know what is going on, or if there is something else I can do to achieve the maximum value in the peak?

  • $\begingroup$ Alright, so I figured out a way to measure the maximum value within the peak: by 'integrating peak from zero'. So this works, however for data with lots of noise, it would still be ideal to obtain the value from a fitted Gaussian and not from the raw data. $\endgroup$
