Flux Calibration Workshop Banner
Description:

Whenever an observation of an astrophysical source must be converted from instrumental values to physical units, we use flux calibration. As new questions are formulated and new capabilities become available, the requirements on the precision and accuracy of flux calibration increase. Once upon a time, 10% was considered good enough, but today, 1% is demanded, which advances in technology and computation power now enable. This workshop addresses current issues in flux calibration for the new generation of telescopes and for multi-wavelength science. In addition, the workshop honors Ralph Bohlin's seminal contributions over 40 years, particularly the development of CALSPEC, the database of spectrophotometric standards used by much of the astronomical research community.

Please join us in Baltimore in March 2020 for a workshop on Accurate Flux Calibration for 21st Century Astrophysics. 

Discussions will include (but are not limited to):

  • More and better stellar atmosphere models
  • UV-VIS absolute flux calibration
  • NIR, MIR FIR absolute flux calibration·        
  • All-sky networks for the future
  • Spectrophotometry
  • The art of flux calibration: Lessons from the past
  • The science of flux calibration:  Progress to the future
  • Laboratory experiments and the quest for SI traceability
  • Can you ever really know your instrument hardware?
  • Flux calibration and cosmology and stellar astrophysics

This workshop is limited to 70 participants. If there is space available, local folks (Maryland and Washington, DC institutions) may attend without registering and are requested to refrain from partaking in the refreshments provided.

The colloquium on Wednesday, March 18, 2020 will be given in conjunction with the workshop, and is open. STScI colloquia are webcast.
