Abstract:
This paper completes the series of cataclysmic variables (CVs)
identified from the Sloan Digital Sky Survey (SDSS) I/II. The
coordinates, magnitudes, and spectra of 33 CVs are presented. Among
the 33 are eight systems known prior to SDSS (CT Ser, DO Leo, HK Leo,
IR Com, V849 Her, V405 Peg, PG1230+226, and HS0943+1404), as well as
nine objects recently found through various photometric surveys. Among
the systems identified since the SDSS are two polar candidates, two
intermediate polar candidates, and one candidate for containing a
pulsating white dwarf. Our follow-up data have confirmed a polar
candidate from Paper VII and determined tentative periods for three of
the newly identified CVs. A complete summary table of the 285 CVs with
spectra from SDSS I/II is presented as well as a link to an online
table of all known CVs from both photometry and spectroscopy that will
continue to be updated as future data appear.
Description:
Spectra obtained in the Sloan Digital Sky Survey (2007 January (DR7) -
2008 June (SDSS II)) and follow-up observations for a few objects
obtained using the Apache Point Observatory (APO) 3.5m telescope and
the Dual Imaging Spectrograph with high-resolution gratings (2Å) in
2009 Feb 24, Mar 29, Apr 18 and 2010 May 5.

Note (1): Note that PQ Gem has a faint red companion (discovery paper is
from EUV; Mason et al. 1992MNRAS.258..749M 1992MNRAS.258..749M). The SDSS spectrum in the
DR9 is attached to the companion, but the spectrum is a compendium of
the two sources. The published paper gives magnitudes of the faintest
red star, but this version gives the magnitudes of PQ Gem (the blue
star in the SDSS image).
Note (2): The 33 objects in DR7 from 2007 January 1 to the conclusion of
SDSS II in 2008 June. The addition of these 33 systems brings the total
spectroscopically identified CVs in SDSS from Papers I-VIII to 285.
Note (3): SDSS photometric measurements are asinh magnitudes (Lupton et
al., 1999AJ....118.1406L 1999AJ....118.1406L) and are normalized (to ∼3% accuracy) to the
AB-magnitude system (Oke and Gunn, 1983ApJ...266..713O 1983ApJ...266..713O ). The ugriz
magnitudes are not corrected for Galactic absorption.
