cds-question@unistra.freffective-temperatureradio-sourcesspectroscopyWe present new full-sky temperature maps in five frequency bands from 23 to 94GHz, based on data from the first 3 years of the WMAP sky survey. The new maps are consistent with the first-year maps and are more sensitive. We employ two forms of multifrequency analysis to separate astrophysical foreground signals from the CMB, each of which improves on our first-year analyses. First, we form an improved "Internal Linear Combination" (ILC) map, based solely on WMAP data, by adding a bias-correction step and by quantifying residual uncertainties in the resulting map. Second, we fit and subtract new spatial templates that trace Galactic emission; in particular, we now use low-frequency WMAP data to trace synchrotron emission instead of the 408MHz sky survey. The WMAP point source catalog is updated to include 115 new sources whose detection is made possible by the improved sky map sensitivity. We derive the angular power spectrum of the temperature anisotropy using a hybrid approach that combines a maximum likelihood estimate at low l (large angular scales) with a quadratic cross-power estimate for l>30. The resulting multifrequency spectra are analyzed for residual point source contamination. At 94GHz the unmasked sources contribute 128+/-27^{micron}^K^2^ to l(l+1)C_l_/2{pi} at l=1000. After subtracting this contribution, our best estimate of the CMB power spectrum is derived by averaging cross-power spectra from 153 statistically independent channel pairs. A simple six-parameter {LAMBDA}CDM model continues to fit CMB data and other measures of large-scale structure remarkably well. The new polarization data produce a better measurement of the optical depth to reionization, {tau}=0.089+/-0.03. This new and tighter constraint on {tau} help break a degeneracy with the scalar spectral index, which is now found to be ns=0.960+/-0.016.2007ApJS..170..288Hhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJS/170/288CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toVIII/40 : GB6 catalog of radio sources (Gregory+ 1996)VIII/38 : The Parkes-MIT-NRAO 4.85GHz (PMN) Surveys (Griffith+ 1993-96)J/AZh/85/483 : Sources from the WMAP catalog (Vol'vach+, 2008)J/ApJS/170/108 : NEWPS_5{sigma}_ Source Catalogue (Lopez-Caniego+, 2007)J/ApJS/148/97 : The WMAP First Year Source Catalog (WMAP1) (Bennett+, 2003)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJS/170/288https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJS/170/288http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJS/170/288https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJS/170/288https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJS/170/288http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJS/170/288GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJS/170/288/table6 (Three-Year Wilkinson Microwave Anisotropy Probe (WMAP) Observations: Temperature Analysis)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJS/170/288/table6?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJS/170/288/table6?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJS/170/288/table6?GETtext/xml+votable180.050000true1.5208-6.36670.005555555555555556WMAP6/18 438 532 556 579 700 911 1521 1701 2143 2331 2414 2836 2951 3918 4285 4695 4770 4820 5154 5448 5458 5546 5596 5693 5767 5804 5817 5848 6252 6496 6618 6853 6984 6996 7391 7394 7426 7606 7652 7851 7873 7896 7911 7969 8031 8299 8485 8858 8948 9403 9442 9460 9545 9566 9612 9633 9636 9676 9688 9723 9976 9998 10006 10163 10186 10249 10288 10294 10422 10432 10435 10548 10743 10983 10986 11052 11396 11408 11430 11605 11631 11639 11640 11715 11880 12047 12173 12241 12352 12466 12580 12604 12619 13273 13352 13367 13496 13687 13722 13789 13927 14150 14520 14842 14854 14858 15023 15067 15286 15916 15936 16027 16049 16059 16093 16170 16281 16298 16301 16509 16655 16962 17019 17048 17184 17215 17351 17414 17541 17579 17927 18002 18005 18035 18158 18365 18378 18506 18624 18661 18669 18766 19088 19101 19190 19398 19593 19609 19622 19629 19890 20099 20290 20725 20783 20881 20888 21049 21055 21121 21215 21266 21768 21924 21934 21968 22100 22305 22363 22375 22396 22658 22808 22917 22950 23099 23121 23127 23306 23323 23469 24571 24608 24796 24845 24906 25016 25196 25255 25300 25630 25677 25748 25864 26131 26292 26374 26550 27060 27310 27322 27417 27423 27714 27764 27765 27939 28167 28479 30140 31176 31399 31430 31451 31509 31559 31664 32247 32657 32764 32841 32892 32961 33549 33560 33684 33827 33862 33881 34013 34086 34095 34104 34123 34210 34264 34428 34461 34494 34517 34571 34572 34675 34870 35079 35294 35432 35440 35501 35562 35801 36100 36139 36155 36333 36941 36945 37385 37474 38128 38169 38189 38277 38279 38763 38800 38916 39562 40060 40354 40474 40527 40730 40777 41041 41051 41059 41072 41088 41310 41335 43233 43366 43806 43822 43936 44170 44247 44776 44805 44897 44908 45011 45158 45446 45614 45648 45763 46055 46101 46174 46204 46214 46251 46310 46337 46373 46764 46964 47016 47100 47106 47107 47268 47534 47540 48123 48496 48595 48798 48846 489651.490865653319302e-23 6.16224470038645e-23https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJS/170/288?format=asciiOpticalRadiodefaultJ/ApJS/170/288/table6Three-Year Wilkinson Microwave Anisotropy Probe (WMAP) Observations: Temperature AnalysisNoteSource note (2)meta.notecharrecnoRecord number assigned by the VizieR team.
