cds-question@unistra.frglobular-star-clustersspectral-energy-distributionThis paper presents accurate spectral energy distributions (SEDs) of 16 M31 globular clusters (GCs) confirmed by spectroscopy and/or high spatial-resolution imaging, as well as 30 M31 globular cluster candidates detected by Mochejska et al., Cat. J/AcA/48/455 (1998). Most of these candidates have m_V_>18, deeper than previous searches, and these candidates have not yet been confirmed to be globular clusters. The SEDs of these clusters and candidates are obtained as part of the BATC Multicolor Survey of the Sky, in which the spectrophotometrically-calibrated CCD images of M31 in 13 intermediate-band filters from 4000 to 10000{AA} were observed. These filters are specifically designed to exclude most of the bright and variable night-sky emission lines including the OH forest. In comparison to the SEDs of true GCs, we find that some of the candidate objects are not GCs in M31. SED fits show that theoretical simple stellar population (SSP) models can fit the true GCs very well. We estimate the ages of these GCs by comparing with SSP models.2006A&A...449..143Mhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/449/143CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toII/262 : BATC Data Release One - BATC DR1 (Zhou+ 1995-2005)J/AJ/127/2579 : Optical ident. of BATC Sky Survey X-ray sources (Zhang+, 2004)J/A+A/397/361 : 15-color BATC photometry of Landolt SA95 field (Zhou+, 2003)J/AJ/122/1718 : Multicolor photometry in Abell 2634 (Yuan+, 2001)J/AJ/112/628 : BATC Color Survey of M67 (Fan+ 1996)J/AcA/48/455 : Globular Clusters in M31 and M33 (Mochejska+, 1998)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/449/143https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/449/143http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/449/143https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/449/143https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/449/143http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/449/143GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/449/143/sources (Globular cluster positions)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/449/143/sources?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/449/143/sources?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/449/143/sources?GETtext/xml+votable180.050000true10.937833341.30338890.0055555555555555566/2623https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/449/143?format=asciiOpticaldefaultJ/A+A/449/143/table1Parameters of the BATC filters and statistics of observations for M 31recnoRecord number assigned by the VizieR team.
