Mango dataset

 All spectra of two seasons are shown in Figure (a). The average spectra of the two batches are shown in Figure (b). The main difference comes from the 400-700 nm, these differences may be due to the different contents of anthocyanins, chlorophyll, and other substances in samples from different seasons. There is a slight difference in the 700-1150 nm. The absorbance of season 1 is higher than that of season 2 near 980 nm. If the source domain calibration model is used directly to predict the target domain spectra, significant errors will occur.
