  We use the spectroscopic data collected by the Magellanic Quasars Survey
(MQS) as well as the photometric V- and I-band data from the Optical
Gravitational Lensing Experiment (OGLE) to measure the physical parameters for
active galactic nuclei (AGNs) located behind the Magellanic Clouds. The
flux-uncalibrated MQS spectra were obtained with the 4-m Anglo-Australian
Telescope and the AAOmega spectroscope (R=1300) in a typical ~1.5-hour visit.
They span a spectral range of 3700-8500 Angstroms and have S/N ratios in a
range of 3-300. We report the discovery and observational properties of 161
AGNs in this footprint, which expands the total number of spectroscopically
confirmed AGNs by MQS to 919. After converting the OGLE mean magnitudes to the
monochromatic luminosities at 5100 Angstroms, 3000 Angstroms, and 1350
Angstroms, we reliably measured the black hole masses for 165 out of 919 AGNs.
The remaining physical parameters we provide are the bolometric luminosities
and the Eddington ratios. A fraction of these AGNs have been observed by the
OGLE survey since 1997 (all of them since 2001), enabling studies of
correlations between their variability and physical parameters.
