  2. AIA Data Levels

  3. AIA Level 1.0 & 1.0q • Pixel corrections such as fixed gain variations, pedestal removal • Integer pixel shifts for alignment between telescopes • Bad pixel maps (both due to pixel defects and cosmic rays) will accompany these images

  4. AIA Level 1.5 • Despiked using the bad pixel maps • Flat-fielded for both telescope and detector variations, • Adjusted for plate scale, sub-pixel registration, and roll errors. • Level 1.5q data is exported to LM for mission operations and event detection. • Level 1.5 data is exported to both LM and SAO as it becomes available.

  5. AIA Level 1.7 (browse) • Derived from Level 1.5 • Resampled or windowed in space and time. • Baseline • Full disk, 1Mpixel images on a forty-second cadence (reducing data volume by at least 64) • Full resolution, 1Mpixel images of up to 9 active regions with the same cadence.

  6. Proposed SU/LM connection • Designed being finalized • Expected to be in place early 2008

  7. AIA Movie & Event System

  8. AIA Event System • Based on Hinode Observation System • Shared components & infrastructure • Further development of feature & event component awaiting NASA funding opportunity

  9. AIA Status • Data levels and algorithms are defined up to 1.7 • Will be Implemented by launch • Additional support will be needed (and is anticipated) to complete the development of higher level products
