Notes. Aper is abbreviated aperture code (0.3×.05N3= 0.3″×0.05″ND3). Spectral Range is in Å. Texp is total integration time of dataset (in s). MJD is U.T. start time of observation. QF is quality factor (average S/N per resel). Vshft is wavelength correction (in km/s) derived by cross-correlation relative to first spectrum listed. Dataset with highest throughput normally is in first position. Cross-correlation template parameters (XC: λ and [Δλ], in Å), if any, are provided for first spectrum, but refer to entire group. Null template ("∼") indicates simple co-addition (no shifts). Values in that column for subsequent datasets are flux scale factors (Fscl) relative to leading spectrum (for which Fscl= 1).
