VizieR Online Data Catalog: Speckle interferometry at SOAR in 2018 (Tokovinin+, 2019)
Abstract
The observations reported here were obtained with the HRCam - a fast imager designed to work at the 4.1 m SOAR telescope (Tokovinin 2018PASP..130c5002T). The camera was mounted on the SOAR Adaptive Module (SAM; Tokovinin et al. 2016AJ....152..116T). However, the laser guide star of SAM was not used (except in 2016 January); the deformable mirror of SAM was passively flattened and the images are seeing-limited. In most observing runs, the median image size was ~0.6". The SAM module contains the atmospheric dispersion corrector. The transmission curves of the HRCam filters are given in the instrument manual. We used mostly the Stroemgren y filter (543/22 nm) and the near-infrared I filter (824/170 nm). A few measures were made in the V (517/84 nm) and R (596/121 nm) filters. The detector is the electron multiplication CCD iXon-888. Observations in 2016 used a different detector (Luca-DL), and the I-band response was 788/132 nm.
