We observed 609 stars in the direction of the cluster up to a limiting magnitude of $V\\sim19$ mag. The star count method shows that the centre of the cluster lies at $\\alpha_{2000}=04^{h}09^{m}36^{s}$, $\\delta_{2000}=49^{\\circ}28^{'}43^{''}$ and its angular size is $r=10$ arcmin. The optical and near-infrared two-colour diagrams reveal the colour excesses in the direction of the cluster as $E(B-V)=0.68\\pm0.06$, $E(J-H)=0.21\\pm0.02$ and $E(J-K_{s})=0.33\\pm0.04$ mag. These results are consistent with normal interstellar extinction values. Optical and near-infrared Zero Age Main-Sequences (ZAMS) provided an average distance modulus of $(m-M)_{0}=10.80\\pm0.13$ mag, which can be translated into a distance of $1440\\pm80$ pc. Finally, using Padova isochrones we determined the metallicity and age of the cluster as $Z=0.015\\pm 0.004$ ($[M/H]=-0.10 \\pm 0.10$ dex) and $\\log (t/yr) = 8.40\\pm0.04$, respectively.", "revisions": [ { "version": "v1", "updated": "2009-11-26T08:29:38.000Z" } ], "analyses": { "keywords": [ "open cluster ngc", "2mass photometric study", "ccd bv", "normal interstellar extinction values", "average distance modulus" ], "tags": [ "journal article" ], "publication": { "doi": "10.1007/s10509-009-0233-1", "journal": "Astrophysics and Space Science", "year": 2010, "month": "Mar", "volume": 326, "number": 1, "pages": 139 }, "note": { "typesetting": "TeX", "pages": 15, "language": "en", "license": "arXiv", "status": "editable", "inspire": 838175, "adsabs": "2010Ap&SS.326..139B" } } }
