(2017) [2017AJ....153..136S]) and is presumably the same object listed in Table 4 as {iota} Hor B, the companion giving rise to the 331.7d orbital period in the Gaia DR3 non-single star table; e = This transiting exoplanet, aka TOI-540 b, has no mass measurement; g = This "exoplanet" is the T dwarf WISEPA J075108.79-763449.6, already included as its own row in Table 4; h = This "exoplanet" is the Y dwarf L 97-3 B (sometimes referred to as WD 0806-661 B), already included as its own row in Table 4; i = This "exoplanet" is the T dwarf ULAS J130041.74+122114.7, already included as its own row in Table 4; j = This "exoplanet" is the late-T/early-Y dwarf e Vir Ab, already included as its own row in Table 4; k = This assumes that the exoplanet candidate {rho} CrB b is real; m = The "c" planet is currently considered controversial by the NASA Exoplanet Archive, so only the "b" planet is considered for inclusion in our mass function analysis; n = This "exoplanet" is the T dwarf HN Peg B, already included as its own row in Table 4; Note (2): Indicates whether the "exoplanets" in this system should be considered in our stellar mass function analysis. Notes regarding period violations indicate objects that are excluded, as these are likely objects formed via a protoplanetary disk. In these cases, we list at least one example of component pairs ("b" vs. "c", "c" vs. "d", etc.) that violate the rule. Note (3): Notes on Note as follows: f = The inner and outer planets do not violate the P_{outer} < 5P_{inner rule}, but the imaging of this youthful system nonetheless shows the debris disk remaining from protoplanetary formation; l = In Table 4, we label the object causing the Gaia DR3 acceleration (from the non-single star list) as CD-51 10924 B. For the purposes of accounting, we will equate that object with this one, GJ 676 A c; o = This object has no mass determination. Note (4): References for the planet mass as follows: 1 = Naef et al.
