ATNF Scientific Software – an overview

1. ATNF Scientific Software – an overview Mark Wieringa – ATNF/Operations/SCA

2. Scientific Software • Observation Software • On-line systems • Caobs, tcs etc.; Monitoring applications • Schedule preparation • atcasched, potf etc. • ATNF Supported Data reduction and Analysis Software • Miriad • Maintenance (MRC) • Development for CABB (MHW) • Livedata/Gridzilla • New developments for improved HIPASS images (MRC) • ASAP (MM) • Pulsar suite [GH, user supported] • AIPS (for VLBI), karma (kvis display) • External data analysis software • No local support apart from installation (& friendly other users) ATUC Meeting Oct 2008

3. Miriad Miriad is the main data reduction package for ATCA data Support is currently split in two parts: • Maintenance, installation, Bug fixes – Mark Calabretta • Ports to current OS’s (Linux, OSX) • Maintain ATNF installations & ftp site for distribution • Respond to bug reports and feature requests ATUC Meeting Oct 2008

4. Miriad Miriad-CABB development project (DMcC,Vince, MarkW,Naomi) • Aims to get miriad to state where we can: • Read CABB data • Calibrate CABB data • Image CABB data • Cope with wide fractional bandwidth effects (divide and conquer) • (with ASKAP) access more advanced algorithms • Current status: • Simulate large CABB data files (with many zoom bands) • Can read data in and inspect it with plotting tools • Can split up wide band into multiple files • Waiting for real CABB data and associated calibration info to proceed with calibration path • Investigating issues with large files (>2GB) ATUC Meeting Oct 2008

5. Livedata/Gridzilla • GASS, HIPASS(2) and ZOA datasets available • Mark Calabretta in cooperation with Lister & Naomi looking at defects in existing calibrated data products • Working on improvements in • Dynamic Range • Tsys calibration • Automated flagging • Continuum subtraction • Significant progress made already, more to come • Datasets will probably be (re-)released next year. ATUC Meeting Oct 2008

6. ASAP • Maintained by Malte Marquarding (20%), currently overseas • ASAP has been pretty stable • most issues revolve around building from scratch on recent Linux releases. • New release due soon, with: • CLASS export facility (as requested by many observers) • CLASS package has features not present in ASAP, • reduced support level for ASAP means it has not anticipated need for these features, resulting in user migration.. • bug fixes accumulated since the last release • fixes to be able to build on the latest flavours of Linux • some minor feature additions ATUC Meeting Oct 2008

7. Pulsar software suite • Several packages maintained by pulsar group (internal and external members) • Packages are under version control, either locally (CVS) or on SourceForge • Vince is sorting out the internal software distribution ATUC Meeting Oct 2008

8. Other software • AIPS • Installations maintained by Chris Phillips, no local development • Required for VLBI reduction • Karma (kvis etc.) • MarkC looks after installation & porting issues, no local development • Other reduction/analysis packages • Available on Linux servers, user driven, little local support • Webtools • Selection of locally developed tools to plan observations and prepare schedules • Maintained by operations staff • Calibrator database, rise/set times, planets, rfi, scheduling, OPAL ATUC Meeting Oct 2008

9. Outlook • CABB getting closer • Effort needed in on-line area • Can’t really start until “interim system” is operational • Miriad development progressing • Needs experience with real CABB data to get serious • Scheduling • Prototype CABB scheduler (web based) available for comment • ASKAP • Exploring commonalities, what we can learn from each other • Software Component Architecture - Services • Running existing telescopes • Looking for reuse/repackaging of software from both sides • Monitoring and control applications • Advanced data reduction algorithms • Try to ease transition of ASKAP into operations in a few years ATUC Meeting Oct 2008
