Table A.1

Voyager imaging data and the post-fit residual statistics.

Reference	Object	Time span	N	Sample RMS	Line RMS
Jacobson (2008, 2009)	Triton	1988–1989	366	0.202	0.171
	Nereid	1989	89	0.333	0.251

Notes. N is the number of the pairs of samples and lines. RMS is the root mean square of the post-fit residuals from our orbit fitting process.
