Fig. 8.
Hα, Hβ, and Fe IIλ5169 velocities as measured from the spectra of iPTF14hls. Left of the vertical dashed line displays measurements for epochs presented by A17, while the late-time velocities from our new spectra are displayed to the right of this line. The Fe line velocity remains constant in time, whereas the Balmer-line velocities continue to decline slowly.
