AIA Level 1 Processing

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
