New orbit fit of 1RXS0342+1216 with the 2020 RV data point. Although RV data have the ability to break the degeneracy in the orientation of the orbital plane, the relative RV between the primary and the secondary in the 2020 epoch was close to 0 km s−1, meaning that we are not able to resolve that degeneracy with our data.
