DEM - Differential Emission Measure - Part 1

Leaders: Mark Weber and Paul Boerner

This is the first of two sessions on using AIA data for thermal (especially DEM) analysis. In this session, we will discuss the techniques and challenges of constraining a DEM using AIA, including instrumental calibration; atomic and plasma physics; spectral codes; and inversion techniques.

Brief Talks

Regina Soufli (~10 min + discussion): Calibration of the EUV bandpasses on AIA
Vinay Kashyap (~20 min + discussion): Overview of atomic physics issues; statistical uncertainties in DEM inversion
Additional brief talks on DEM inversion techniques/applications welcome

Discussion Topics

In addition to the discussion of the specific issue raised in the talks, we will attempt to cover some of the broader issues, such as:

What is the best way to identify and track the uncertainties in DEMs obtained from AIA data?
What can be done to reduce the uncertainties involved in the instrument calibration, abundances, line strengths, and other atomic/plasma physics issues that go into DEM analysis?
What inversion techniques are likely to prove most appropriate for AIA?
