Scientific Rationale:

This focus meeting aims to bring together active researchers to discuss recent advances in the area of calibrations and standardization, to share successes and failures, and to foster a community of support in solving the challenging problems of calibration and standardization common to many different projects for which accurate and precise calibration and standards are vital to their success. This is a cross-disciplinary topic of impact on stellar physics, galactic and extragalactic astrophysics, solar physics; solar system among others fields, and involves instrumentation, observational techniques (photometry, spectroscopy, polarimetry) and multi-wavelength domain.

This Focus Meeting’s goals are to provide a global, in-depth overview and documentation on the current state of the science of calibration in this critical area of modern astronomy. Many individual missions/facilities hold periodic calibration workshops or conferences, however these are by necessity focused on the specific needs of their projects. Discussions on worldwide efforts to establish new standard sources, or on standard software package in central location to be used by many astronomers, rather than individual software packages on individual computers, or on data format standards, or the synergies between projects need a worldwide framework well provided by an IAU GA.



  • Minimum standards for spectrophotometric calibration in the UV, visible and IR
  • Complex issues such as cross instrument and cross survey calibration
  • Establishing faint, SI-traceable spectrophotometric and polarimetric standards
  • SI-traceable characterization of research instrumentation (ground and space)
  • Calibration of complex spectroscopic systems
  • Progress in stellar properties and atmosphere models for calibration work
  • Data management with large datasets and surveys
  • Calibration and standardization of solar-type analogues and twins
  • Radial velocity standards and wavelength calibration
