Abstract:
    We present 5201 radial-velocity (RV) measurements of 1144 stars as
    part of an ongoing study of the young (150Myr) open cluster M35
    (NGC 2168). We have observed M35 since 1997, using the Hydra
    Multi-Object Spectrograph on the WIYN 3.5m telescope.

Note (1): WOCS = WIYN Open Cluster Study.
   Source 23013 shows a systemic trend in the radial velocities, though
   the derived e/i value is below 4.
Note (2): Source of photometry as follows:
   1 = wide-field CCD images centered on M35, taken by T. von Hippel
       with the Kitt Peak National Observatory (KPNO) Burrell Schmidt telescope
       on 1993 November 18 and 19.
   2 = BV photometry of C. P. Deliyannis (2006, private communication), taken
       on the WIYN7 0.9m telescope with the S2KB 2K by 2K CCD. This photometry
       derives from a mosaic of five fields. Each field has a 20'x20' field
       of view, with one central field and four tiled around the center, for
       a total field of view of 40'x40'.

   We note that source 2 photometry is more precise than that of source 1.
   The star-by-star difference in V magnitudes for the two sources is roughly
   Gaussian with σ=0.06mag. However, there is a tail that extends beyond
   three times this sigma value. Therefore, we caution the reader when using
   magnitudes from source 1.
Note (3): the classes are as follows:
     BM = binary member (membership probability from γ-RV is ≥50%)
     BN = binary non-member (membership probability from γ-RV is <50%)
    BLM = binary likely member (no orbital solution)
    BLN = binary likely non-member (no orbital solution)
     BU = binary with unknown membership
     SM = single member star (membership probability from RV is ≥50%)
     SN = single non-member (membership probability from RV is <50%)
      U = unknown membership status
Note (4): These identification numbers are *not* those of Meibom et al.
    (2009ApJ...695..679M) as indicated in the paper.
