(e.g., @2001AJ....122..549V) Ly$\alpha$ at 1216Å, H$\delta$ at 4101Å, H$\gamma$ at 4340Å, H$\beta$ at 4861Å, H$\alpha$ at 6563Å, magnesium MgII at 2800Å, carbon CIV at 1549Å and CIII\] at 1909Å, as well as the narrow forbidden lines of oxygen \[O II\] at 3727Å, \[O III\] at 4959Å or 5007Å. In general, we required the identification of two lines, except in the redshift range $0.7 < z < 1.2$, where we can only find MgII despite the broad spectral coverage.

New Quasars {#sec:newquasars}
===========

We identified [144 ]{}new quasars behind the LMC. Their basic parameters (including the identified lines) are presented in Table 3. We also confirmed the [25 ]{}known quasars that were in our target list (Table 4). Of these known quasars, we had flagged four only as probable quasars because their spectra were too noisy for reliable classification. We missed one known quasar, MQS J051140.7$-$710032.8, that had extremely low S/N in our data, although we verified its existence. These five sources are reported at the bottom of Table 4.

The newly discovered quasars cover the range of redshifts $z=0.15$–$3.35$ as shown in Figure \[fig:hist\]. The deficit at $z\approx 0.8$ is probably due to problems in convincingly identifying quasars based on
