VizieR Online Data Catalog: Transiting planet WASP-4b (Southworth+, 2019)
Abstract
Twenty-two high-quality light curves of transits of the extrasolar planetary system WASP-4 are presented and used to confirm the existence of transit timing variations in the system. They were obtained using the 1.54m Danish Telescope at ESO La Silla, Chile, the 3.6m NTT at ESO La Silla, Chile, and the 40-inch telescope at Sutherland, South Africa. The filters used were Cousins R for the Danish and Sutherland telescopes, and SDSS r for the NTT. The errorbars for each transit have been scaled so the best-fitting model (obtained using the JKTEBOP code) has a reduced chi-squared value of 1.0.
