Notes.

(a)

We refer the reader to Anderson (2019) for the detailed orbital solution of α UMi using VELOCE data.

Identifiers and magnitudes were compiled from SIMBAD, Gaia mean G-band magnitudes from the Gaia archive, and pulsation periods from Paper I. Column “Status” indicates whether a star’s SB1 nature was newly discovered (“New”), or previously known or suspected (“Known” or “Susp”). Stars listed as Susp among newly discovered SB1 systems were considered tentative previously. References to previous studies are abbreviated using alphanumeric codes as follows. R1: R1Evans & Udalski (1994), R2: R2Evans (1994), R3: R3Lloyd Evans (1982), R4: R4Petterson et al. (2004), R5: R5Kovtyukh et al. (2015), R6: R6Anderson (2013), R7: R7Szabados (2003), R8: R8Szabados & Pont (1998), R9: R9Szabados et al. (2013a), R10: R10Anderson et al. (2016a), R11: R11Griffin (2016), R12: R12Anderson et al. (2015), R13: R13Evans (1995), R14: R14Bersier et al. (1994), R15: R15Evans (1991), R16: R16Gallenne et al. (2019), R17: R17Szabados (1996), R18: R18Evans et al. (1990), R19: R19Evans (1992), R20: R20Gorynya et al. (1996a), R21: R21Wahlgren & Evans (1998), R22: R22Pont et al. (1994), R23: R23Gallenne et al. (2013), R24: R24Szabados (1992), R25: R25Madore (1977), R26: R26Gieren (1982), R27: R27Szabados et al. (2014), R28: R28Turner et al. (2007), R29: R29Russo et al. (1981), R30: R30Bersier (2002), R31: R31Szabados et al. (2013b), R32: R32Anderson (2019), R33: R33Gorynya et al. (1996b). The stars with “VELOCE” in the “References” column are cases where VELOCE data was previously used to establish the binarity or the orbit. Column “Evidence” states whether we determine a combined model for orbit and pulsation (“Orbit”), determine a trend in the pulsation residuals (“Trend”), or whether template fitting involving literature RV data indicates a time-variable vγ (“RVTF-Yes”) or not (“RVTF-No”). The last column “Triple?” indicates whether the star is likely part of a triple system, usually involving a visually resolved companion.
