VizieR Online Data Catalog: Polarization of LMXB MAXI J1820+070 (Kosenkov+, 2020)
Abstract
Nightly average observed polarisation degrees (PD) and polarisation angles (PA), obtained during the 2018 outburst of MAXI J1820+070. Polarimetric measurements were performed using Dipol-2 polarimeter (Piirola et al., 2014, Proc. SPIE Conf. Ser. Vol. 9147, p. 91478I) mounted on the Tohoku 60cm telescope (T60) at Haleakala observatory, Hawaii. Dipol - 2 is a remotely operated "double - image" CCD polarimeter, which is capable of recording images in three(BVR) filters simultaneously. The innovative design of the polarimeter, where the two orthogonally polarised images of the sky overlap on the images of the source, allows to completely eliminate the sky polarisation at an instrumental stage (even if it is variable), and to achieve unprecedentedly high, up to 10-5, accuracy of target polarimetric measurements (Piirola 1973A&A....27..383P, Berdyugin, 2019, Astrophysics and Space Science Library, Vol. 460, p. 33).
