VizieR Online Data Catalog: Speckle interferometry at the OAN-SPM Mexico (Guerrero+, 2021)
Abstract
Our observations were carried out using the 2.1m telescope of the OAN-SPM, during five runs allocated in 2018 and 2019. In every observing run we used an iXon Ultra 888 camera from ANDOR technology, coupled to a filter wheel containing the three broadband filters that we typically use, V, R, and I, with the effective wavelengths centered at and widths of 538/90, 630/130, and 894/340nm (for each filter, respectively), which provide diffraction-limited resolutions of 0.053", 0.067", and 0.088", respectively.
