Abstract:
    We confirm 66 low-mass stellar and brown dwarf systems (K7-M9) plus 19
    visual or spectroscopic companions of the {beta} Pictoris moving group
    (BPMG). Of these, 41 are new discoveries, increasing the known
    low-mass members by 45%. We also add four objects to the 14 known with
    masses predicted to be less than 0.07 M_{sun}_. Our efficient
    photometric + kinematic selection process identified 104 low-mass
    candidates, which we observed with ground-based spectroscopy. We
    collected infrared observations of the latest spectral types (>M5) to
    search for low-gravity objects. These and all <M5 candidates were
    observed with high-resolution optical spectrographs to measure the
    radial velocities and youth indicators, such as lithium absorption and
    H{alpha} emission, needed to confirm BPMG membership, achieving a 63%
    confirmation rate. We also compiled the most complete census of BPMG
    membership, with which we tested the efficiency and false-membership
    assignments using our selection and confirmation criteria. Using the
    new census, we assess a group age of 22+/-6 Myr, consistent with past
    estimates. With the now-densely sampled lithium depletion boundary, we
    resolve the broadening of the boundary by either an age spread or
    astrophysical influences on lithium-burning rates. We find that 69% of
    the now-known members with AFGKM primaries are M stars, nearing the
    expected value of 75%. However, the new initial mass function for the
    BPMG shows a deficit of 0.2-0.3 M_{sun}_ stars by a factor of ~2. We
    expect that the AFGK census of the BPMG is also incomplete, probably
    due to biases of searches toward the nearest stars.

Description:
    To summarize, we combined astrometry and photometry from USNO-B1.0
    (Monet et al. 2003, Cat. I/284), 2MASS (Skrutskie et al. 2006,
    Cat. VII/233), SDSS DR9 (Ahn et al. 2012, V/139), DENIS (Epchtein et al.
    1994Ap&SS.217....3E, see B/denis), and UCAC3 (Zacharias et al. 2010,
    Cat. I/315). These data yielded proper motions from the astrometry and
    spectral types (SpTs) and bolometric fluxes from spectral energy
    distribution (SED) fitting of the photometry for all sources in those
    catalogs. To concentrate our search on the most probable candidates,
    we narrowed our input sample using two spatial cuts. First, to avoid
    crowding and its effects on the inferred stellar properties, we neglected
    sources near the galactic plane and center (|b|<5{deg}, or |b|<10{deg}
    and 310{deg}<l<50{deg}). Second, to focus our consideration on the locus of
    known BPMG members (Figure 1), we disregarded targets with 7h<{alpha}<18h.

Note (2): We first computed the kinematic distance modulus (DM_kin_) that would
          minimize the difference between a source's observed proper motion and
          the expected proper motion for a BPMG member at that position on the

      2009, J/ApJ/699/649).
Note (5): Membership status as follows:
   VB = Visual binary;
  SB1 = Unresolved binarity;
  SB2 = Double-lined spectroscopic binary;
  SB3 = Triple-lined spectroscopic binary.
Note (6): Literature references for binarity are as follows:
  1 = Nicholson (2015, Binary star discoveries in the URAT1 catalog);
  2 = Malo et al. (2014, J/ApJ/788/81);
  3 = Liu et al. (2010SPIE.7736E..18L);

  8 = Janson et al. (2014, J/ApJS/214/17);
  9 = Bowler et al. (2015ApJ...806...62B).
Note (7): Uncertainties in the EW of Li are typically less than 0.05 {AA} and
          in H{alpha} are 0.1 {AA}.
Note (8): UVWs and XYZs are not reported for nonmembers, as the kinematic
          distance used in the calculations of these values is meaningless if
          they are not actual members.
Note (9): Note as follows:
  h = These SBs have system RVs consistent with the BPMG, strong H{alpha}
      emission, and inconclusive Li observations. To avoid biasing the sample
      away from SBs, we designate them "Y?". These systems should be followed up
      for full orbital solutions and/or parallaxes to better understand their
      ages;
  i = Schlieder et al. (2010, J/AJ/140/119) reported an RV of 10.4+/-2.0 km/s
      and a {Delta}RV of 3.8 km/s and thus considered this a likely BPMG member;
  j = Binks & Jeffries (2016MNRAS.455.3345B) reported H{alpha} in absorption and
      thus rejected this star as a BPMG member.
Note (10): The first reference to list these targets as BPMG members:

Note (2): Lists the assessment of each age diagnostic and membership status
          following the prescription of this paper, as summarized in Figure 3.
          We subjected the 123 published members with K and M SpTypes to the
          same tests described in Sections 3-5 as a test of the methodology.
          The results of those tests are summarized in the text.

Global notes:
Note (G1): Allers & Liu (2013ApJ...772...79A) define spectral indices and
   pseudo-equivalent widths (EWs) of various gravity-sensitive features in 
   lower-resolution NIR spectra to classify the spectra into three groups: 
   low (VL-G), intermediate (INT-G), and high (FLD-G) gravity objects, 
   roughly corresponding to young (~<30Myr), intermediate (~30-200Myr), 
   and field-age (>~200Myr) objects.
Note (G2): Membership assessment as follows:
  Y = Confirmed member;
  N = Nonmember when the kinematics or youth indicators conflict with
      membership;
  ? = Likely member whose RV differ from the predicted values due to binarity
      in the system.
