N A W G ======= NRAO Algorithms Working Group Meeting - PRELIMINARY AGENDA Date: 2005-2-09 (Wednesday) Time: 1300 MST = 1500 EST Video Hub: CV-conf (others call in) Rooms: SOC317/CV311/GB241/TUCN505 I would like to invite you to attend and participate in the second NRAO Algorithms Working Group (NAWG) meeting on Wednesday 9 February 2005. The goal of these meetings is to have a general forum to discuss data-processing algorithms related issues of interest to scientists and software folks alike (independent of development platform or package). This is in response to the pressures of planning for the EVLA hard problems like wide-field/wide-band imaging as well as thinking about problems for ALMA and GBT. It is meant to be as observatory-wide as possible and I'm trying to solicit some participants from the various sites. These meetings are meant to be mostly informal discussion with some scheduled presentations ("Main Events") on algorithmic research and/or implementation topics. If you wish to participate and also want to speak on a topic let me know (or just show up either in person or via video/audio)! NOTE: These meetings were originally scheduled for the 4th Wednesday each month (in the NAUG meeting slot in the calendar), but we have moved these to the 2nd Wednesday NAUG time instead for scheduling reasons. ======= Agenda: Send items for inclusion to smyers 1. Organizational issues o goals of the NAWG, topics for future meetings (Steve) 2. Project-related (ALMA, EVLA, GBT, VLBA, &c.) algorithms o LWA issues and plans (Steve, Sanjay, others) 3. General algorithmic issues o Astronomy Science Data Model (ASDM) update (Ed) 4. ***Main Event*** - Presentations and Discussion Items ******************************************************************* o Bill Cotton - single dish image processing and calibration of GBT data ******************************************************************* 5.
