The cluster has a highly elongated morphology with fractal distribution of stars. The core and cluster radii of the cluster are estimated as 0.5 and 1.2pc, respectively. We have identified 45 stars as cluster members using the Gaia proper motion data. The distance and age of the cluster are found to be 3.5+/-0.9kpc and 0.9^+0.3^_-0.1_Gyr, respectively. The slope of the mass function '{Gamma}' in the cluster region, in the mass range ~0.95<M/M_{sun}_<2.2, is found to be -1.01+/-0.43. The cluster shows the signatures of mass segregation and is dynamically relaxed (dynamical age = 10Myr). This along with its small size, big tidal radius, low density/large separation of stars, and elongated and distorted morphology indicates that the Cz3 is a loosely bound disintegrating cluster under the influence of external tidal interactions.2020MNRAS.498.2309Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/498/2309CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toI/345 : Gaia DR2 (Gaia Collaboration, 2018)II/349 : The Pan-STARRS release 1 (PS1) Survey - DR1 (Chambers+, 2016)II/246 : 2MASS All-Sky Catalog of Point Sources (Cutri+ 2003)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/498/2309https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/498/2309http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/498/2309https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/498/2309https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/498/2309http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/498/2309GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/498/2309/table1 (the NIR photometry of the stars in this study)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/498/2309/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/498/2309/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/498/2309/table1?GETtext/xml+votable180.050000true15.7622088962.793190.005555555555555556Cone search capability for table J/MNRAS/498/2309/table3 (45 stars identified as cluster members)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/498/2309/table3?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/498/2309/table3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/498/2309/table3?GETtext/xml+votable180.050000true15.8004480662.774238890.0055555555555555566/37157.952274030004205e-20 3.916500758235022e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/498/2309?format=asciiOpticalInfrareddefaultJ/MNRAS/498/2309/table1the NIR photometry of the stars in this studye_JmagError on Jmagmagstat.error;phot.magfloatHmagH-band magnitudemagphot.mag;em.IR.Hfloate_HmagError on Hmagmagstat.error;phot.magfloatKmagK-band magnitudemagphot.mag;em.IR.Kfloate_KmagError on Kmagmagstat.error;phot.magfloatrecnoRecord number assigned by the VizieR team.
