Technical Issues and Challenges

Example: Positional correlation of objects in a region of the sky across multiple wavelengths (Radio, IR, Optical, UV, X-rays, Gamma Rays)

• Data volume and network bandwidth

  • Cache of pre-computed results (e.g., astronomical catalogs)
  • Data filtering at data site, ship results only (see poster)
  • Deployment of user code (platform independent S/W) or RPI
  • Data visualization for exploration and selection

• Registration, Sensitivity, Positional Accuracy

  • Coordinate transformation (on a large scale)
  • Calibration and normalization
  • “Guide stars” for VOF registration?
