Okumura(NRO,NAO-J), Satoru Iguchi(NAO-J), Yoshihiro Chikada(NAO-J), Munetake Momose(Ibaraki University), Mahoko Okiura(The University of Tokyo/NRO,NAO-J 2002/08/15 Keywords: 2-nd generatin correlator, spectroscopic observations, Orion-KL The first astronomical fringe of a test correlator for the Atacama Large Millimeter/Submillimeter Array (ALMA) is obtained. The newly-developed test correlator system consists of two 4096-Msps Analog-to-Digital Converters (ADCs) and an FX-type correlator that can divide a 2-GHz correlation signal from one baseline into 131072 frequency channels. A fringe spectrum that contains 20 line features as well as continuum emission at $\sim 86.2$ GHz was obtained by an interferometric observation of the Orion-KL regions using this test system connected to the Nobeyama Millimeter Array (NMA), demonstrating that the realization of high frequency resolution over a wide bandwidth is technically feasible. The installation of such a correlator system in the ALMA will greatly enhance its capability of multi-line imaging.

References: <3D611287.1020208@nrao.edu> Message-ID: <3D61429A.7000006@nrao.edu> Following from today's discussion, as a trial, we have re-enabled the Calender function of SiteScape and put it on the front SS page: http://almaedm.tuc.nrao.edu/forums/alma/dispatch.cgi/meetcalend It is set to be open access for now ie anyone can upload a meeting to the calender. Its fairly self-explanatory (I managed to work it out myself). Some hints: - add a meeting with the "Add Entry" button. - to add a meeting over several days, select the start date and Repeat: Yes and choose number of days. - select "All-Day" for non-specific times. - to delete or modify entry, click on date, then meeting title. - to list all events in a table (rather than calender) select "Search", press "OK" ie leave fields blank. - you can add a URL link to a document ie agenda etc SS has several features which will allow individual groups/IPTs to have their own calenders and these calenders to be merged at the users choice with other and the project wide calenders. We will start with this one general calender for a trial. For now, continue to send Carloyn the details of your meetings as per her email request.
