Abstract:

UBV photoelectric photometry for 175 stars in the field of the southern open cluster NGC2323, supplemented by DDO photometry of 5 probable giants, is presented. The analysis of the photometric data yields 109 probable members; one of them being a red giant, and 3 possible members. The reddening across the cluster is slightly variable and the mean value E(B-V)=0.25. The apparent cluster distance modulus is 10.62, corresponding to a distance of 940 pc. The age, determined by fitting isochrones with core overshooting, turns out to be Myr. Other fundamental cluster parameters are also determined. NGC2323 appears not to be physically connected to the CMa OB1 association.

What is OpenURL?

The OpenURL standard is a protocol for transmission of metadata describing the resource that you wish to access. An OpenURL link contains article metadata and directs it to the OpenURL server of your choice. The OpenURL server can provide access to the resource and also offer complementary services (specific search engine, export of references...). The OpenURL link can be generated by different means.

If your librarian has set up your subscription with an OpenURL resolver, OpenURL links appear automatically on the abstract pages.
You can define your own OpenURL resolver with your EDPS Account. In this case your choice will be given priority over that of your library.
You can use an add-on for your browser (Firefox or I.E.) to display OpenURL links on a page (see http://www.openly.com/openurlref/). You should disable this module if you wish to use the OpenURL server that you or your library have defined.
