			Abbreviation & Description \\
			\midrule
			$\max(|\cos|)$ & Variation of the cut that excludes the boundary regions of the Dalitz plot. \\
			Efficiency & Two efficiency modelling uncertainties added in quadrature: using an alternative parameterization, and accounting for the
							    limited size of the simulated event sample. \\
			Joint & Uncertainty obtained by simultaneously fitting disjoint sub-sets of the dataset, separated by the year of data-taking and type
                                of  $ K\xspace\xspace^0_{\rm\scriptscriptstyle S}$ \xspace daughter track, with distinct efficiency models. \\			
			Weights & Three uncertainties related to the re-weighting of simulated events used to generate the efficiency model  $\varepsilon\xspace( m^{2}_{ K\xspace\xspace^0_{\rm\scriptscriptstyle S}\xspace\pi\xspace\xspace}\xspace,  m^{2}_{ K\xspace\xspace\pi\xspace\xspace}\xspace)$ \xspace, added in quadrature.
							 These account for: incorrect simulation of the underlying $ p\xspace\xspace p\xspace\xspace$ interaction, uncertainty in the relative yield of long
							 and downstream  $ K\xspace\xspace^0_{\rm\scriptscriptstyle S}$ \xspace candidates, and uncertainty in the efficiency of selection requirements using information from the
							 RICH detectors. \\
			Comb. & Using an alternative combinatorial background model. \\
			 $ -2\log\mathcal{L}$ \xspace & Using a more complex alternative model where the threshold in $\Delta( -2\log\mathcal{L}\xspace)$ for a resonance to be retained is reduced to $9$ units. \\
			Flatt\'{e}\xspace & Variation of the Flatt\'{e}\xspace lineshape parameters for the  $ a\xspace_{0}(980)^{{\pm}}$ \xspace resonance according to their nominal uncertainties. \\
			$f_{\text{m}}, f_{\text{c}}$ & Variation of the mistag and combinatorial background rates according to their uncertainties in the mass fit. \\
			$d_{ D\xspace\xspace^0\xspace}, d_{ R\xspace}$ & Variation of the meson radius parameters. \\
			$T_{\rho\xspace\xspace^{\pm}}$ & Switching to a Breit-Wigner dynamical function to describe the  $\rho\xspace\xspace(1450,1700)^{{\pm}}$ \xspace resonances. \\
