Session S2: Irradiance and EUV Calibrations
Thursday, Feb 16
10:30 - noon
Session Organizers: Paul Boerner, Frank Eparvier, Rock Bush

Introduction: 
 - Solar observations in the EUV during SDO (Boerner) (5 min)
 - Calibrations in the EUV (Eparvier) (5 min)

Topic 1: EUV cross-calibrations between SDO (AIA and EVE) and non-SDO instruments

Brief (3-5 minutes; 1-3 slides) presentations on other EUV instruments that
can be cross-calibrated with SDO instruments are welcome as a starting point 
for discussion. We’ll hope to get preliminary answers to the following questions:

 - What is needed (coordination, data products) to cross-calibrate EIS and EVE?
 - What is needed to cross-calibrate EIS and AIA?
 - What is needed to cross-calibrate TRACE/EIT/EUVI and AIA?
 - What can be gained from these cross-calibrations?

Topic 2: AIA and EVE cross-calibration

We’ll discuss the details of AIA and EVE cross-calibration in order to get a sense of how to answer the following questions:

 - What data products are needed from AIA and EVE to cross-calibrate?
 - What sort of planning/coordination of cross-calibration observations needs to be done?
 - How will the cross-calibration be implemented?
 - How will we handle updates to the calibration (from rocket underflights, etc.)?
 - How accurate do we expect this cross-calibration to be? 
 - How accurate does it need to be?
