This sample is selected according to the criteria for E+A galaxies defined by Goto, and each of these objects is further visually identified. In this sample, most objects are low redshift E+A galaxies with z<0.25, and are located in an area of the sky with high Galactic latitude and magnitude from 14 to 18mag in the g, r and i bands. A stellar population analysis of the whole sample indicates that the E+A galaxies are characterized by both young and old stellar populations (SPs), and the metal-rich SPs have relatively higher contributions than the metal-poor ones. Additionally, a morphological classification of these objects is performed based on images taken from the Sloan Digital Sky Survey.2015RAA....15.1414Yhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/other/RAA/15.1414CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toV/146 : LAMOST DR1 catalogs (Luo+, 2015)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/other/RAA/15.1414https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/other/RAA/15.1414http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/other/RAA/15.1414https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/other/RAA/15.1414https://vizier.iucaa.in/viz-bin/votable?-source=J/other/RAA/15.1414http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/other/RAA/15.1414GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/other/RAA/15.1414/table12 (list of E+A galaxies from LAMOST DR2 (table 1)and photometric features (table 2))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/other/RAA/15.1414/table12?https://vizier.iucaa.in/viz-bin/conesearch/J/other/RAA/15.1414/table12?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/other/RAA/15.1414/table12?GETtext/xml+votable180.050000true167.7442969428.677291940.0055555555555555566/926 1163 2153 2331 2364 4518 4574 4960 4985 5221 5239 5542 5668 8269 8585 8620 8933 9035 9082 9098 9133 10285-10286 10379 10400 10515 10815 10874 10894 10916 17644-17645 17648 17650-17651 17662 17784-17785 17873 18004 18151 18897 18903 18923-18924 19528 19539 25565 26196 26280 26593 27052 27062 27098 27654 28149 28251 28283 28369 28383 28412 28414 285232.040811542443644e-19 6.090060298487514e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/other/RAA/15.1414?format=asciiOpticaldefaultJ/other/RAA/15.1414/table12list of E+A galaxies from LAMOST DR2 (table 1)and photometric features (table 2)SimbadNameSimbad column added by the CDSmeta.idcharnullableSeqSequential numbermeta.recordintrecnoRecord number assigned by the VizieR team.
