Around the RT of the input feature, a time window is constructed which results in a local XIC. The peak apex is then located in this local XIC. The log_L_R metric measures the skewness of the peak around the RT of the obtained apex point. The SNR metric provides the ratio of peak height to noise, where the noise value is set as the lowest intensity value in the local XIC
