cds-question@unistra.fropen-star-clustersphotometryWe construct an integrated spectrum of the intermediate-age, solar-metallicity Galactic cluster M67, from individual spectroscopic observations of bona fide cluster members. The spectrum so obtained is used as a template to test our stellar population synthesis models, in an age and metallicity regime where such models remain largely untested. As a result, we demonstrate that our models predict a spectroscopic age of 3.5+/-0.5Gyr for M67, which is the same age we obtain from fitting isochrones to the color-magnitude diagram of the cluster. Full consistency is reached when using either H{beta}, H{gamma}, or H{delta} as the age indicator. We also check if the models, when applied to the cluster integrated spectrum, predict elemental abundances in agreement with the known detailed abundance pattern of the cluster. The models also pass the latter test, by predicting the abundances of iron, magnesium, carbon, and nitrogen in agreement with detailed abundance analyses of cluster stars to within 0.1dex. Encouraged by the high degree of consistency of our models, we apply them to the study of the integrated spectrum of the central 3" of the compact elliptical galaxy M32.2004AJ....127.1513Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/127/1513CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/AJ/106/181 : CCD photometry of open cluster M67 (Montgomery+ 1993)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/127/1513https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/127/1513http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/127/1513https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/127/1513https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/127/1513http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/127/1513GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AJ/127/1513/table1 (Stars not found to be members on M67)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/127/1513/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/127/1513/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/127/1513/table1?GETtext/xml+votable180.050000true132.587916712.35319440.005555555555555556Cone search capability for table J/AJ/127/1513/table2 (Stars found to be members of M67 and used in the construction of the cluster integrated spectrum)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/127/1513/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/127/1513/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/127/1513/table2?GETtext/xml+votable180.050000true133.040145211.7794150.005555555555555556Cone search capability for table J/AJ/127/1513/table6 (Lick indices measured in the spectra of field and M67 Stars)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/127/1513/table6?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/127/1513/table6?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/127/1513/table6?GETtext/xml+votable180.050000true84.9681152.8974880.0055555555555555566/1873 4255 4296 4298 4772 6196 6510 6705 6852 10595 21726 21809 25198 27457 27756 31073 31411 31751 40692 44669https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AJ/127/1513?format=asciiOpticaldefaultJ/AJ/127/1513/table1Stars not found to be members on M67NameStellar identification (1)charprimaryrecnoRecord number assigned by the VizieR team.
