Photometric precision
WebThe Kepler photometric mission measured high-precision pho-tometric variations of stellar flux on 160 000 stars (down to ˘10 ppm) and allowed (up to now) the detection of 1235 planet transit candidates (Borucki et al. 2011). Howard et al. (2011) extensively analyzed the published datasets and established the WebDec 7, 2024 · The derived photometric precision (repeatability) at bright unsaturated fluxes varies between 8 and 25 millimag. The high end of these ranges corresponds to an airmass approaching ∼2—the limit of the public survey. Photometric calibration accuracy with respect to Pan-STARRS1 is generally better than 2%.
