Using the 6.5m Magellan Telescope at the Las Campanas Observatory in Chile, we have acquired deep B and I images in four fields (0.44deg each in diameter), yielding accurate photometry for 1068893 stars down to 24th magnitude, with a spatial resolution of 0.20arcsec per pixel. Colour-magnitude diagrams and (completeness-corrected) luminosity functions have been constructed, yielding significant new results that indicate at least two discrete star formation events over a period from 2.7 to 4Gyr ago. Also, we have derived star formation rates as a function of look-back time and have found enhancements of SF between 4 and 6Gyr and at younger ages.2019MNRAS.489.5087Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/489/5087CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/489/5087https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/489/5087http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/489/5087https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/489/5087https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/489/5087http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/489/5087GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/489/5087/table3 (Catalogue of detected sources)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/489/5087/table3?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/489/5087/table3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/489/5087/table3?GETtext/xml+votable180.050000true13.8190101932-72.11543011130.0055555555555555566/33294-33295 33317 333282.367228618189496e-19 5.042107639525881e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/489/5087?format=asciiOpticaldefaultJ/MNRAS/489/5087/table3Catalogue of detected sourcesrecnoRecord number assigned by the VizieR team.
