We confirm L 113 as a relatively old and metal-poor cluster, and report for the first time that L 110 and 112 are also relatively old clusters (t~6.5Gyr) . Their derived ages and metallicities reinforce previous suggestions that the farther a cluster is from the centre of the galaxy, the older and more metal-poor it is, with some dispersion. In addition, the bursting star formation model still appears to be the most probable paradigm to describe the SMC's star formation history. We call attention to a second possible burst at ~6-7Gyr, besides the known burst at ~3Gyr.2007MNRAS.381L..84Phttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/381/L84CatalogResearchIsServedByTAP VizieR generic servicerelated-toJ/ApJS/101/41 : SMC and Bridge extended catalog (Bica+ 1995)JMNRAS/382/1203 : CT1 photometry of 5 SMC star clusters (Piatti+, 2007)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/381/L84https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/381/L84http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/381/L84https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/381/L84https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/381/L84http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/381/L84GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticaldefaultJ/MNRAS/381/L84/table2CCD CT1 data of stars in the field of L110recnoRecord number assigned by the VizieR team.
