Posterior samples and SNR calculations associated with <em>Identifying LISA verification binaries among the Galactic population of double white dwarfs</em> (arxiv:2210.10812, MNRAS, 522, 5358 (2023)). The <code>data</code> folder contains the following: <code>vb_table</code>: Verification binary (VB) candidate properties obtained from electromagnetic (EM) observations. This data was compiled by Kupfer et al. and is available at https://gitlab.in2p3.fr/LISA/lisa-verification-binaries (accessed on 2022 September 2). Used in Table 1. <code>snr</code>: SNR calculations for each VB candidate as a function of mission duration. Used in Figure 2. <code>basic</code>: Gravitational-wave (GW) parameter estimation study of each VB candidate. Used in Table 2 and Figure 3. <code>detection_time</code>: VB SNR calculations with source property (and LISA launch time) uncertainty taken into account. Used in Figure 1 and Figure 4. <code>em_priors</code>: GW parameter estimation study with EM information included in the priors. Used in Figure 5. <code>unknown_noise</code>: GW parameter estimation study with the inclusion of noise parameters to vary the PSD. Used in Figure 6. <code>filtered_populations</code>: Source properties of DWDs nearby in frequency to each VB candidate. See the <code>confused_sources.ipynb</code> notebook. Used in Figure 7. <code>confusion_snr</code>: SNR calculations of the above confusion sources. Used in Figure 7. <code>confusion</code>: A analysis of V803Cen with a realistic Galactic population of DWDs included in the data. Used in Figure 8. Code to reproduce every figure from the paper is available in <code>plots</code>. Supplementary notebooks associated with the generation of a realistic data instance (i.e. including a simulated Galactic population of DWDs nearby in frequency to V803Cen) can be found in <code>notebooks</code>.
