Note (2): Defined as f_{lambda}_ {prop to} {lambda}^-GammaUV^.
GammaUV is fitted at {lambda}_rest_<4200{AA}. Slopes with no listed
errors show the assumed slope value in cases where only a single
continuum window was available.
Note (3): Defined as f_{lambda}_ {prop to} {lambda}^-GammaOpt^.
GammaOpt is fitted at {lambda}_rest_>4200{AA}.

135-136 I2 --- NAbs Number of narrow absorption features used
in the emission line modeling
-------------------------------------------------------------------------------
Note (1): Based on the uncertainties in the amplitude and FWHM of the Gaussian
model and do not include an error from an uncertainty in the
underlying continuum flux level which we estimate to be about 10%.
For emission lines where only an upper limit on Flux and EW is
available, no values for the VPeak are quoted as the position of the
line was fixed at the line's expected wavelength. Also, the FWHM
value in this case was set to the median value for the LBQS sample
(see Table 3, Paper~II) with no associated errors.

Global notes:
Note (G1):
Based on the equinox J2000 position (in standard IAU format
consisting of HHMM+/-DDMM). In addition to this, a two letter
designation is used for the spectra indicating that the spectra are
from a post-COSTAR observation (o) and whether there is
more than one spectrum of the same object (a-z). A capital
letter at the end of the name indicates that the object is
a gravitational lens and that separate spectra of each
lensed component were observed and analyzed.
