VizieR Online Data Catalog: Asteroseismology for solar analogues 16 Cyg A/B (Davies+, 2015)
Abstract
Both 16 Cyg A and B are brighter (V~6) than the saturation limit for which Kepler observations were designed. However, it was possible to capture the full stellar flux by using custom photometric aperture masks. Thus, 928 d of short-cadence observations (Gilliland et al. 2010ApJ...713L.160G) - from Quarter 7 to 16 - were generated using simple aperture photometry (Jenkins et al. 2010ApJ...713L..87J) and then corrected for instrumental perturbations following the methods described by Garcia et al. (2011MNRAS.414L...6G). The final light curves used for asteroseismic analyses were high-pass filtered using a triangular smooth of 4 d width and have a duty cycle of 90.5 per cent. The power density spectra were computed using a Lomb-Scargle algorithm.
