We present a set of low resolution empirical SED templates for AGNs andgalaxies in the wavelength range from 0.03 to 30 microns based on themulti-wavelength photometric observations of the NOAO Deep-Wide Field SurveyBootes field and the spectroscopic observations of the AGN and Galaxy EvolutionSurvey. Our training sample is comprised of 14448 galaxies in the redshiftrange 0<~z<~1 and 5347 likely AGNs in the range 0<~z<~5.58. We use ourtemplates to determine photometric redshifts for galaxies and AGNs. While theyare relatively accurate for galaxies, their accuracies for AGNs are a strongfunction of the luminosity ratio between the AGN and galaxy components.Somewhat surprisingly, the relative luminosities of the AGN and its host arewell determined even when the photometric redshift is significantly in error.We also use our templates to study the mid-IR AGN selection criteria developedby Stern et al.(2005) and Lacy et al.(2004). We find that the Stern etal.(2005) criteria suffers from significant incompleteness when there is astrong host galaxy component and at z =~ 4.5, when the broad Halpha emissionline is redshifted into the [3.6] band, but that it is little contaminated bylow and intermediate redshift galaxies. The Lacy et al.(2004) criterion is notaffected by incompleteness at z =~ 4.5 and is somewhat less affected by stronggalaxy host components, but is heavily contaminated by low redshift starforming galaxies. Finally, we use our templates to predict the color-colordistribution of sources in the upcoming WISE mission and define a colorcriterion to select AGNs analogous to those developed for IRAC photometry. Weestimate that in between 640,000 and 1,700,000 AGNs will be identified by thesecriteria, but will have serious completeness problems for z >~ 3.4.
