Abstract:

A large scale survey of the Galactic center region in the () transition is presented. This survey was obtained with the 1.2m Southern Millimeter-Wave Telescope (SMWT) at the Cerro Tololo Interamerican Observatory (CTIO) near La Serena, Chile. It covers the region and with a grid spacing of 9, i.e. the sampling is at full FWHP beamwidth. 357 positions were in total observed. After reviewing the instrumentation of the 1.2m SMWT, the observing techniques, and the methods used in the data reduction, the data of the survey are presented and morphologically described. In addition, data of the HNCO(5_0,5-4_0,4) line are presented, which was also included in the large bandwidth of the spectrometer. measurements performed for comparison purposes are presented and compared with other ¹²CO results. The maps of the survey demonstrate that there are great differences between the distribution of the optically thin emission and the usually optically thick emission.

What is OpenURL?

The OpenURL standard is a protocol for transmission of metadata describing the resource that you wish to access. An OpenURL link containsarticle 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.
