Calibration targets for astronomical polarimetry for the 0.3 to 30 μm wavelength range
Dates: 23-24 January 2013
Location: Institute of Astronomy, HIT building, J-Floor, ETH Zurich, Science City Hönggerberg, Wolfgang-Pauli-Str. 27, CH-8092 Zurich, Switzerland
SOC: Stefano Bagnulo, Mathieu Barthelemy, Silvano Fineschi, Herve Lamy, Arturo Lopez Ariste, Hans Martin Schmid (chair), Frans Snik.
LOC: M. Chiesi, H.M. Schmid
Outline: New science opportunities are opened for astronomical polarimetry by large ground-based telescopes and new instruments. However, some of these instruments require better or new polarimetric measuring and calibration strategies. This workshop will address the polarimetric calibration requirements of modern and future polarimetric measurements. The need for better on-sky calibration and test targets shall be discussed and new initiatives for establishing better calibration targets and better calibrated polarimetric instruments shall be proposed and discussed.
Workshop goals:
- Review the measuring and calibration limits of existing and future polarimetric instruments
- Compile information from the community on polarimetric calibration targets (via questionnaire)
- Identify needs for new, more or better calibration targets for astronomical polarimetry
- Initiate new observing programs for better calibration targets with improved parameters
The scientific report of the meeting is available here in PDF format.
