True color visualization of the central lantern based on the hyperspectral image (b), together with PCA false color renderings (a, c). a R, G, B correspond to: PC1—45.23% retained variance, PC2—36.55% variance, PC3—7.3% variance. b R, G, B correspond to the most informative spectral bands: 650 nm, 551 nm and 470 nm. c R, G, B correspond to: PC5—2.47% retained variance, PC6—10.97% variance, PC4—5.53% variance
