cds-question@unistra.frvariable-starsradial-velocityeffective-temperatureA sequence search method was developed for searching for regular frequency spacing in {delta} Scuti stars by visual inspection (VI) and algorithmic search. The sample contains 90 {delta} Scuti stars observed by CoRoT. An example is given to represent the VI. The algorithm (SSA) is described in detail in section 3.2. The data treatment of the CoRoT light curves, the criteria for frequency filtering, and the spacings derived by two methods (i.e., three approaches: VI, SSA, and FT (Fourier Transform)) are given for each target. Echelle diagrams are presented for 77 targets for which at least one sequence of regular spacing was identified. Comparing the spacing and the shifts between pairs of echelle ridges revealed that at least one pair of echelle ridges is shifted to midway between the spacing for 22 stars. The estimated rotational frequencies compared to the shifts revealed rotationally split doublets, triplets, and multiplets not only for single frequencies, but for the complete echelle ridges in 31 {delta} Scuti stars. Using several possible assumptions for the origin of the spacings, we derived the large separation ({Delta}_nu_) that are distributed along the mean density versus large separations relation derived from stellar models.2016ApJS..224...41Phttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJS/224/41CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toB/corot : CoRoT observation log (N2-4.4) (CoRoT 2016)J/A+A/559/A63 : Photometric frequencies of HD 174966 (Garcia Hernandez+, 2013)J/A+A/543/A125 : Spectral types of CoRoT stars (Guenther+, 2012)J/A+A/541/A34 : Spectral types of stars in CoRoT fields (Sebastian+, 2012)J/A+A/528/A147 : CoRoT 101155310 light curve (Poretti+, 2011)J/other/A+ARV/18.67 : Accurate masses and radii of normal stars (Torres+, 2010)J/A+A/506/519 : Supervised classif. of CoRoT variables (Debosscher+, 2009)J/A+A/506/471 : Frequency analysis of CoRoT B stars (Degroote+, 2009)J/A+A/506/79 : Asteroseismic analysis of HD 174936 (Garcia Hernandez+, 2009)http://idoc-corotn2-public.ias.u-psud.fr/ : CoRoT N2 public archivehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJS/224/41https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJS/224/41http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJS/224/41https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJS/224/41https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJS/224/41http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJS/224/41GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJS/224/41/table2 (List of our sample)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJS/224/41/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJS/224/41/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJS/224/41/table2?GETtext/xml+votable180.050000true100.7097167-1.375750.0055555555555555566/22076 22078 22079 22122 22164 22165 22167 22208 22210https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJS/224/41?format=asciiOpticaldefaultJ/ApJS/224/41/table2List of our samplerecnoRecord number assigned by the VizieR team.
