Astro-WISE

an Astronomical Wide-field Imaging System for Europe E v e r y o n e John P. McFarland OmegaCEN, Kapteyn Astronomical Institute Groningen, NL 20 November 2006LC2006 Workshop

Other Data Sources ● No real OmegaCAM data yet ● Vast amounts of public archive data ● Plenty of sky to analyze and calibrate ● Feed the Information System ● Support Everyone in Astro-WISE

Data Sources ● Current Optical Data Sources – OmegaCAM (test data only) – WFI – WFC (one config) – MDM8K – SUP (one config) ● Potential Data Sources – HST ACS, VIMOS, MOSAIC I & II, IMACS, MegaCAM,..., VISTA, Pan-STARRS, LSST

Multi-Config ● Originally only one configuration supported – Chip geometry (NAXIS1, NAXIS2) – Focal plane geometry (astrometry) – Header layout (keywords) ● Multiple configurations needed – Dynamic instrument lay-outs – Software changes – Hardware changes

HeaderTranslator ● Raw data interface to AWE ● Makes all data uniform ● Front-end for multiple configurations – Feed signature to HeaderTranslator – Use dictionaries to return correct configuration – Adaptive RawFrame.make() ● Remaps chip geometry ● Masks invalid regions with non-numbers – Bring all configurations to uniformity

Geometry Remapping

PyFitsIO ● Non-number aware replacement to Eclipse ● Uses NumArray and PyFits instead of qfits ● Currently performance limited – Impending system upgrades will help solve this – NumPy and SciPy’s Weave library ● /

Summary ● Astro-WISE is ready ● Single configurations fully supported ● Multiple configurations will be supported – Need PyFitsIO
