Polarimetry

The position angle of the polarisation when using FAPOL is wavelength dependent. This was measured and the results are provided on the ALFOSC web pages so people can correct for this effect.

A post-processing procedure is being developed that would automatically analyse linear polarisation data taken with FAPOL and provide a polarisation estimate for all the stars in the field of view.
