Radial velocity fits from the data gathered in Table 6 used to constrain dynamical masses for the binaries. The binaries are listed from left to right in the figure as J0437 and J0459 on the first top row; J0532 and J0613 on the second row from the top; J0728 and J0916 on the third row from the top; and J2317 on the bottom row. The shades of grey represent the first, second and third sigma intervals of the values predicted by the fit for each epoch, where sigma is the standard deviation.
