VizieR Online Data Catalog: HST/ACS flux time series for HD 189733 (Pont+, 2007)
Abstract
We monitored three transits of the giant gas planet around the nearby K dwarf HD 189733 with the ACS camera on the Hubble Space Telescope. The resulting very-high accuracy light-curve (signal-to-noise ratio near 15000 on individual measurements, 35000 on 10-min averages) allows a direct geometric measurement of the orbital inclination, radius ratio and scale of the system: i=85.68+/-0.04, Rpl/R*=0.1572+/-0.0004, a/R*=8.92+/-0.09.
