Birds of a Feather (BoF) Sessions
ADASS XVII will feature 4 Birds of a Feather (BoF) sessions. BoFs are informal sessions created by attendees on topics of special interest. The following BoFs have been scheduled:
BoF 1: Monday, 19:30-21:00 (Great Hall)
FITS
W. Pence and the IAU FITS Working Group
This Birds-of-a-Feather session will present a summary of current activities related to the FITS data format and will provide a forum for the discussion of current issues. Main topics of discussion will be
- the proposed revisions and updates to the FITS Standard document
- issues related to the Registry of FITS Conventions, either in regard to particular conventions, or regarding the structure and procedures of the Registry itself
- progress in the past year on extending the World Coordinate Systems conventions to Time coordinate systems, and to describing distortions in idealized coordinate systems.
There will be an open forum at the end for short presentations on any other FITS-related topics.
BoF 2: Monday, 19:30-21:00 (Small Hall)
Transient Event Reporting and Response with VOEvent
R. Seaman, A. Allan, R. Williams
Abstract:
Evanescing astronomical phenomena will be key to dramatic scientific discoveries over the next decades. Large telescopes such as LSST and Pan-STARRS will survey the time domain with unprecedented breadth and depth. Networks of nimble robotic response telescopes yearn like locusts anticipating their next meal. A common language for describing observations of transients must span from synoptic discovery to robotic follow-up and through to VO-driven characterization. VOEvent is that lingua franca.
The IVOA VOEvent working group is engaged with the larger astronomical and software communities to develop the VOEvent language and conforming technologies through workshops and BoFs. In addition to brisk status reports from various autonomous astronomy projects, we will wrangle entertainingly over hot topics:
- How to publish your event stream
- How to connect to event streams
- Autonomous response with HTN
- Time series representation
- Event distribution from the LSST firehose
- Controlled vocabulary for event types
- Representing orbital elements
- Authentication and trust for events
- Querying event repositories
- Support for traditional event publications (GCN, CBAT, MPC, ATEL)
- Transport backbone architecture
- Classification and coincidence testing
- Multipart event messages
Dedicated delvers can discern diverse and detailed VOEvent links:
- IVOA VOEvent working group
- VOEventNet consortium
- Heterogeneous Telescope Networks consortium
- Hot-wiring the Transient Universe
Representatives of projects in time domain astronomy are encouraged to contribute presentations to the BoF and their expertise to the working groups.
BoF 3: Tuesday, 17:15-18:45 (Great Hall)
Data Mining for Large Scale Astronomical Datasets: Challenges, Milestones and Solutions
S. McConnell, S. Williamson, A. Howes
Abstract:
The session will provide ADASS participants with an opportunity to obtain an overview of existing work in the application of data-mining techniques to astronomical data, identify challenges, discover possible solutions, present research results, contribute their own experiences, express their concerns, and discuss the general issues associated with data-mining of large-scale astronomical datasets. Furthermore, this session will facilitate collaboration between researchers and professionals from different fields, including Astronomy, Computer Science IT. As one of the featured topics for ADASS 2007, data-mining as the focus of this BoF is of utmost relevance to the conference.
Timeline:
- Introduction to the Current State of the Application of Data-Mining Techniques to Astronomical Data (Sabine McConnell, Presentation, 15 minutes plus time for questions)
- Overview of Parallel and Distributed Programming Techniques and Challenges (Scott Williamson, Presentation, 15 minutes plus time for questions)
- Issues in Pre-Processing (Annelie Howes, Presentation, 15 minutes plus time for questions)
- Parallel and Distributed Data-Mining Techniques (optional, Sabine McConnell, Presentation, 15 minutes plus time for questions)
- Short contributions by participants in the form of short presentations, to be solicited after acceptance of the session.
- Which astronomical problems and/or data are suitable for data-mining applications?
- How can surveys facilitate the data-mining process?
- Identification of major challenges and possible solutions
- Identifications of possibilities for collaboration etc.
BoF 4: Tuesday, 17:15-18:45 (Small Hall)
IRAF Users and Developers
M. Fitzpatrick, F. Valdes, R. Seaman, N. Zarate
Abstract:
IRAF development within the NOAO Data Products Programs (DPP) has recently been resumed in support of other DPP efforts such as the NVO and pipeline processing. This development will provide new releases of external packages, the core IRAF system and the X11IRAF tools that will be of interest to the wider user community. Support for these new projects, how feedback from users helps drive new development, and a new collaboration between the user-community hosted by IRAF.net and NOAO/DPP projects define a new model for the future of IRAF development.
We propose a BoF session for IRAF users and developers that will serve as a "Town Hall" style meeting to answer questions that the above statements will surely raise, as well as a more traditional BoF with prepared presentations from the organizers and as those solicited from the community with plenty of time reserved for Q&A. Specific topics to be covered include:
- Status and plans for the IRAF.net web site.
- IRAF Development within NOAO and what it means for users.
- Overview of new software releases, including:
- What's new in IRAF and future plans
- Developing your own NVO Applications in IRAF (new)
- IR data reduction in IRAF (new)
- X11IRAF Developments
Presentations on relevant material from individual users and projects teams will be welcome. Software discussed at this BoF will be available at the NOAO Demo table throughout the meeting.
