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

4
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

5
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

6
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
8
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 SciPys Weave library
• http//www.scipy.org/PerformancePython/

Summary

• Astro-WISE is ready
• Single configurations fully supported
• Multiple configurations will be supported
• Need PyFitsIO
