Streaming Tool Evaluation

The first iteration of the eSDO StreamingTool prototype was released on 14 July 2006 as a java webstart application. The streaming tool can be launched from http://msslxx.mssl.ucl.ac.uk:8080/esdo/visualization/jnlp/esdo_streamingtool.jnlp. The tool has been demonstrated formally and informally during July, August and September 2006. The following feedback was obtained at an eSDO coronal wave community meeting, SOHO-18, and the HELAS Roadmap workshop. These feature requests and bugs will guide development over the remaining 12 months of eSDO project time.


1st Iteration: July 2006

  • Java webstart application
  • AstroGrid integration: PLASTIC-enabled to view image data located through HelioScope
  • Spatial pan and zoom enabled

2nd Iteration: December 2006

  • Temporal pan and zoom: step forward, step back, forward movie mode, rewind movie mode
  • Save static images as GIFs or JPEGs
  • Save image series as IDL datacube or movie (MPEG or animated GIF)



  • Temporal pan should use "grab and drag" (similar to Google maps) instead of direction arrows
  • Streaming tool java webstart does not work on Macs
  • Simple java class reads FITS file image data, so solar images do not have colour, and in the case of MDI magnetograms, no gaussian min / max to show magnetic differences

Suggested Functionality

  • Add coronal wave analysis: FFT? Display power spectrum?
  • Overlay multiple wavelengths? Display different wavelengths as a collage?
  • Add eSDO algorithms: show coronal loops? show small events? show CME dimming regions?
