Calibration of the polarimeter CasPol at the Nasmyth focus: Application to two extragalactic sources
Abstract
In this work we present the results of the analysis of photo-polarimetric data obtained with the instrument CasPol at the Nasmyth focus of the {Jorge Sahade} 2.15~m telescope, {at} CASLEO. We also study different {polarized and unpolarized standard} stars to characterize this instrument when it is used in {the aforementioned focus}. The results of this characterization were applied to calibrate the data from two extragalactic sources: PKS 0625-35 and 1RXS J084702.1-23.
