Four observations of star 46. Only a small region of the spectrum around Ca II λ8542 is shown. The wavelengths are corrected for slit mis-centering, and they are shown in the heliocentric frame. The red dashed line shows the expected center of the line at the mean velocity of Tri II: ﹩\langle {v}_{\mathrm{helio}}\rangle =-381.7﹩ km s−1. The blue dotted lines show the center of the line at the measured velocity for each observation. The blue whiskers surrounding the blue dotted lines reflect the uncertainty in the position of the line center. The four observations show significant variation, indicating that the star’s velocity is variable.
