Scheme for Involving Students with Data

• Data are preprocessed at Caltech
• Locate showers
• Reconstruct
• Display using GIS

• Data can be provided at variety of levels
  appropriate to grade and knowledge of students
• Students can access raw data, shower archives
• Independent student research projects
• Refereed e-journal

(Still under development we have not been
funded for these activities yet )
