PolarBase: a data base of high resolution spectropolarimetric stellar observations
9 pages, 6 figures International audience PolarBase is an evolving data base that contains all stellar data collected with the ESPaDOnS and NARVAL high-resolution spectropolarimeters, in their reduced form, as soon as they become public. As of early 2014, observations of 2,000 stellar objects throug...
