Notes.;

^(a)

Radial velocity due to the rotation of the Earth, the motion of the Earth about the Earth-Moon barycenter, and the motion of the Earth around the Sun

^(b)

measured in one nod position;

^(c)

for the science spectra the S/N is measured in the telluric-corrected spectrum, note that the S/N decreases from chip 1 to chip 4;

^(d)

integrated flux sensitivity limits are given for a spectrally unresolved line of width 3.3 km s^-1 and a line of width 20 km s^-1.
