Notes. Aper is abbreviated aperture code (0.2×.05N2= 0.2″×0.05″ND2). Spectral Range is in Å. Texp is total exposure time (in s). MJD is first start time of a sequence. QF is quality factor (average S/N per resel). Vshft is wavelength correction (in km/s) derived from pair-wise cross-correlations. XC are cross-correlation template parameters (λ and [Δλ], in Å). Cross-correlation, if any, was applied between template spectrum and preceding one. If no template params are reported ("∼") beyond first spectrum, "blind" coaddition (no relative shifts) was performed. Fscl is flux scale factor bootstrapped from overlap zones with reliable flux ratios, relative to spectrum with best apparent throughput (Fscl= 1).
