The mean SED requires a bolometric correction (relative to 2500{AA}) of BC_2500{AA}_=2.75+/-0.40 using the integrated light from 1um-2keV, and we further explore the range of bolometric corrections exhibited by individual objects. In addition, we investigate the dependence of the mean SED on various parameters, particularly the UV luminosity for quasars with 0.5&lt;~z&lt;~3 and the properties of the UV emission lines for quasars with z&gt;~1.6; the latter is a possible indicator of the strength of the accretion disk wind, which is expected to be SED-dependent.</description><source format="bibcode">2013ApJS..206....4K</source><referenceURL>https://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJS/206/4</referenceURL><type>Catalog</type><contentLevel>Research</contentLevel><relationship><relationshipType>IsServedBy</relationshipType><relatedResource ivo-id="ivo://CDS.VizieR/TAP">TAP VizieR generic service</relatedResource></relationship><relationship><relationshipType>IsServedBy</relationshipType><relatedResource>Conesearch service</relatedResource></relationship><relationship><relationshipType>related-to</relationshipType><relatedResource ivo-id="ivo://CDS.VizieR/VII/269">VII/269 : SDSS Quasar Catalog, DR9Q (Paris+, 2012)</relatedResource><relatedResource ivo-id="ivo://CDS.VizieR/II/319">II/319 : UKIDSS-DR9 LAS, GCS and DXS Surveys (Lawrence+ 2012)</relatedResource><relatedResource ivo-id="ivo://CDS.VizieR/II/311">II/311 : WISE All-Sky Data Release (Cutri+ 2012)</relatedResource><relatedResource ivo-id="ivo://CDS.VizieR/V/139">V/139 : The SDSS Photometric Catalog, Release 9 (Adelman-McCarthy+, 2012)</relatedResource><relatedResource ivo-id="ivo://CDS.VizieR/II/312">II/312 : GALEX-DR5 (GR5) sources from AIS and MIS (Bianchi+ 2011)</relatedResource><relatedResource ivo-id="ivo://CDS.VizieR/VII/258">VII/258 : Quasars and Active Galactic Nuclei (13th Ed.)
