Zeeman-Doppler imaging of active stars. III. Instrumental and technical considerations.
Abstract
An account is given of the instrumental setup and observational procedure that led to the qualifying of Zeeman-Doppler imaging and to new detections of magnetic fields on four stars HR 1099, sigma2 CrB, II Peg and UX Ari.
