 5. V_mag        - V-magnitude from SIMBAD.
 6. Sp_Type      - spectral type from SIMBAD.
 7. P_rot        - rotation period (day) [4, 5, 6].
 8. KWS          - link to the KWS database [7] for this object.
 9. Cycle-1      - cycle 1 from [1, 2].
10. Cycle-2      - cycle 2 from [1, 2].
11. LC (KWS)     - link to the light courve (LC) and V magnitude with calculated JD (V-data) from this site.
