Notes. Columns show: 1) structure (pixel) ID number; 2) absolute value of the Galactic radial velocity of the pixels at positive and negative vR; 3) azimuthal velocity of both pixels; 4) median metallicity of the pixel at positive vR; 5) 95% confidence range for the median metallicity of the pixel at positive vR; 6) same as 4 but for the pixel at negative vR; 7) same as 5 but for the pixel at negative vR; 8) difference between median metallicities: Δ [M/H] = [M/H] 1− [M/H] 2; 9) approximate significance of the difference (Eq. (2)); 10) number of stars in the circle of 10 km s-1 around the pixel at positive vR; 11) same as 10 but for the pixel at negative vR; 12) associated moving group.
