We also present the selection functions for each of the 12 data sets, similarly homogenised. The total sample spans redshifts from z=0 to 7.5. The paper presents a detailed description of the combined sample and determinations of the AGN UV luminosity function throughout this redshift range. The code for developing and analysing AGN luminosity functions is available on GitHub (https://github.com/gkulkarni/QLF). The inferred UV luminosity functions can also be used to derive the contribution of AGN to the cosmic UV background and its effect on the intergalactic medium (IGM). The GitHub repository also includes code for this. Here we also present the luminosity functions in redshift bins, luminosity function evolution models from the paper, the 912{AA} and 1450{AA} volume emissivity of AGN from z=0 to 15, and the hydrogen photoionization rate contribution by AGN in this redshift range.</description><source format="bibcode">2019MNRAS.488.1035K</source><referenceURL>https://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/488/1035</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>related-to</relationshipType><relatedResource ivo-id="ivo://CDS.VizieR/J/AJ/131/2766">J/AJ/131/2766 : Quasar luminosity function from SDSS-DR3 (Richards+, 2006)</relatedResource><relatedResource ivo-id="ivo://CDS.VizieR/J/ApJ/710/1498">J/ApJ/710/1498 : QSO luminosity function at z~4 (Glikman+, 2010)</relatedResource><relatedResource ivo-id="ivo://CDS.VizieR/J/MNRAS/392/19">J/MNRAS/392/19 : The 2dF-SDSS QSO survey (Croom+, 2009)</relatedResource><relatedResource ivo-id="ivo://CDS.VizieR/J/ApJS/199/3">J/ApJS/199/3 : The quasars MMT-BOSS pilot survey (Ross+, 2012)</relatedResource><relatedResource ivo-id="ivo://CDS.VizieR/J/ApJ/768/105">J/ApJ/768/105 : z~5 QSO luminosity function from SDSS Stripe 82</relatedResource><relatedResource ivo-id="ivo://CDS.VizieR/J/MNRAS/449/4204">J/MNRAS/449/4204 : WFC3/UVIS quasar-stacked spectrum at z=~2.4 (Lusso+, 2015)</relatedResource><relatedResource ivo-id="ivo://CDS.VizieR/J/ApJ/829/33">J/ApJ/829/33 : Luminous of high-z QSOs with SDSS and WISE.
