Appendices
Nearly all the identifications of spectroscopic binaries in the target list are drawn from attributions in the 2015 Washington Double Star Notes file. After publication, the USNO astronomers informed me that the source (author) of these attributions, and the references used to compile them, are unknown.
87	remark for H V 17	replace "#x2299;" with sol symbol
87	data, remark for Σ 61	change label from "65 i" to "65" and move data and remark from Andromeda to Pisces (p. 146)

90	data for β 265	replace SAO "104750" with "—"
91	data for S 749	replace spectral types "F7V+G2V" with "F7V F6V"

107	data for Rhd 1	replace "(AaAb) B (CaCb)" with "(AaAb) B C" (a possible brown dwarf companion to proxima Centauri is probably spurious). In the remarks, replace "(2)+1+(2) spectroscopic quintuple, visual triple" with "(2)+1+1 spectroscopic quadruple, visual double" and replace "the C binary" with "the C component"
109	remark for Σ 13	replace "m.11 double" with "m.11 pair"
111	Cetus	due to a data processing error the double star OΣ 45 (02 41.0 +04 52, 7.4 9.0, θ = 263°, ρ = 0.8", distance = 90*, A9V, HD 16721, SAO 110680) was omitted from the target list

132	data for Δ 178	change label "Δ 178" to "B 1267"

148	data for Σ 1120	magnitudes should read "5.6, 9.7, 10.0, 9.8, 11.7". position angles are "37, 41, 327, 7"; other columns shift one column to the right
155	Taurus	due to a data processing error the triple star 31 Tau (Kui 15, (AaAb) B, 03 52.0 +06 32, 6.3 6.6, θ = 204°, ρ = 0.8", distance = 240, B5V, HD 24263, SAO 111469) was omitted from the target list
