VizieR Online Data Catalog: Speckle interferometry at SOAR in 2016 and 2017 (Tokovinin+, 2018)
Abstract
The observations reported here were obtained with the high-resolution camera (HRCam) - a fast imager designed to work at the 4.1 m SOAR telescope (Tokovinin & Cantarutti 2008PASP..120..170T; Tokovinin 2018PASP..130c5002T). For practical reasons, the camera was mounted on the SOAR Adaptive Module (SAM, Tokovinin et al. 2016PASP..128l5003T). However, the laser guide star of SAM was not used (except in 2016 January) because it was not needed and, moreover, reduced the productivity by adding an overhead. The deformable mirror of SAM was passively flattened and the images are seeing-limited. The SAM module contains the atmospheric dispersion corrector (ADC) and helps to calibrate the pixel scale and orientation of HRCam (see SOAR14). The transmission curves of HRCam filters are given in the instrument manual. We used mostly the Stromgren y filter (543/22 nm) and the near-infrared I filter (788/132 nm).
