Image Gallery


The eSDO Image Gallery creates a gallery of thumbnail images with basic observation metadata from URLs pointing to solar FITS files. The Image Gallery can be launched as a Java Webstart file from http://msslxx.mssl.ucl.ac.uk:8080/esdo/visualization/jnlp/esdo_imagegallery.jnlp, and it uses the VOTech PLASTIC standard to load FITS file sourced through the AstroGrid Helioscope tool.


  1. Launch the AstroGrid Client Runtime tool (ACR).
  2. Start Helioscope from the ACR.
  3. Enter start and stop times, ensure "Graphics" is ticked, and press "Search". Once Helioscope locates available STAP services matching search times, click on an instrument name to find FITS files by time.
  4. Launch the Image Gallery tool.
  5. Press "Register".
  6. In Helioscope, "View images in ESDO Image Gallery" will appear. Double click on one or more FITS files, and then click "View images in ESDO Image Gallery" once.
  7. In the Image Gallery tool, press "Gallery".
  8. A thumbnail image of each FITS file will be displayed in a gallery along with basic observation metadata.

Future Enhancements

  • Migration to browser-based tool with direct query to STAP service to take advantage of server-side processing.
  • Standard pre-processing for SDO files (such as colour addition) before thumbnails are generated.
  • Optional: addition of grid lines and coordinate information on thumbnails.
