APOGEE CCFs for 2M17204248+4205070, transformed from lag units into velocity space. The blue and red dashed lines represent the Lorentzian fits to the primary and secondary velocity peaks, respectively; the sum of the two fits is shown as a green dot-dashed line, and the residuals of the fit are shown as an orange dot-dashed line, offset by 0.1 for clarity. Note the spurious secondary fits in the third and fourth rows at epochs with MJDs of 56049, 56052, and 56351. Erroneous velocity values associated with spurious fits such as these have been removed from our data set by visual inspection.
