VizieR Online Data Catalog: Polarization monitoring of 2MJ21392676+0220226 (Manjavacas+, 2023)
Abstract
We conducted linear polarimetric imaging photometry of 2M2139+0220 by using the zSPECIAL+43 filter and the FOcal Reducer and low-dispersion Spectrograph 2 (FORS2), which is mounted on the Antu unit (UT1) of the Very Large Telescope (VLT) of the European Southern Observatory (ESO) in Cerro Paranal, Chile. FORS2 is by default equipped with a detector system that is optimized for the red with a very low level of fringes thanks to a mosaic of two 2048x4096MIT CCDs (with 15μm pixels). The plate scale is 0.252"pixel for the standard readout mode (2x2 binning). The central wavelength and the passband of the zSPECIAL+43 filter are 916 and 18nm, respectively.
