Rationale
Our objective is to explore the issues needed to tie the calibration of telescopes together, across a wide wavelength range, both at ground-based and space-based observatories. Progress in astrophysics is now tied to powerful models of a variety of phenomena, and to test those models, we need precisely and accurately calibrated observations across the electromagnetic spectrum. The topic of calibration has not been covered by an IAU Symposium. It is usually covered in focused workshops (such as at the IAU General Assembly in 2018) or facility specific meetings. The last meeting which could be described as general was hosted at Fermilab in 2012. Most calibration meetings are small and mission-focused, and by design cannot meet our objective.We plan to bring observational and theoretical astrophysicists together to discuss the issues we face to give us a common working framework for current and future endeavours.
