Ca triplet spectral feature. The BRUCE model photospheric spectrum (black) is plotted alongside the averaged normalized spectrum observed by ESPaDOnS (red) and the difference between the two, which represents the pure emission component (blue). Both the observed and pure emission spectrum show that the Paschen lines Pa16, Pa15, and Pa13 blended with calcium emission CaII λ8498, 8542, and 8662, respectively, are much stronger than the emission from the unblended Paschen lines.
