\subsection{Line fitting}
We perform Voigt profile fitting of the calcium II H \& K lines after dividing out the continuum spectrum and, in the case of the calcium II H lines, dividing out the Sersi\'c fit to the strong H$\epsilon$ line, which is centered at 230 km/s LSR in the calcium II H frame. The
column densities were determined by simultaneously fitting Voigt profiles to both lines of the Ca II doublet with the \texttt{VPFIT} software \footnote{Available at \href{http://www.ast.cam.ac.uk/~rfc/vpfit.html}{http://www.ast.cam.ac.uk/$\sim$rfc/vpfit.html}}. The Ca II line close to the Milky Way rest
frame is best fit with two Voigt profile components centered at $v_{LSR} \,\approx$ -6 and
8 km/s, respectively. The redshifted high-velocity
lines are each absorption component is best fit with two
Voigt profile components
in each of the the two Ca II lines. centered at $v_{LSR}\, \approx$ 94 and 100 km/s, respectively. All four
fits individual Voigt profile compoents to Ca II K components agree with the equivalent Ca II H parameters to within errors.
The individual Voigt profile fits are reported in Table \ref{Table:Voigt_Fit} and are shown in Figure 3.
