C}}$ is the cross-section equivalent diameter, i.e., the diameter of a sphere with the same cross section, of the $i$-th component at the observed aspect. Since the aspect is changing over time, the given value is an average over all lightcurve sessions. To quantify the mean aspect we used an asterocentric latitude of a Phase Angle Bisector (PAB), which is the mean direction between the heliocentric and geocentric directions to the asteroid. As discussed in Harris et al. (1984), this is an approximation for the effective viewing direction of an asteroid observed at non-zero solar phase. The average absolute value of the asterocentric latitude of the PAB (computed using the nominal pole of the mutual orbit, assumed to be the rotational pole of both components) was 27 deg.

$D_{i,{\rm V}}$ is the volume equivalent diameter, i.e., the diameter of a sphere with the same volume, of the $i$-th component. $D_{2,{\rm C}}/D_{1,{\rm C}}$ is the ratio between the cross-section equivalent diameters of the components. $P_i$ is the rotational period of the $i$-th component.

An analysis of the best subset of data for the secondary rotation taken from 2018-06-07.9 to -11.0 gave a formal best-fit estimate for the secondary rotation period of
