Notes.

^(a)

assumed number of QSO/deg²;

^(b)

survey size;

^(c)

scaling factor applied to the noise level, i.e. 0 means no noise and 1 noise corresponding to BOSS nominal setup;

^(d)

indicates whether the effect of peculiar velocities was taken into account or not;

^(e)

rms for the isotropic BAO scale;

^(f)

transverse BAO scale;

^(g)

radial BAO scale;

^(h)

significance of BAO feature detection.
