Help with EPIC 220522664

  • ProtoJeb21 by ProtoJeb21

    I recently did a re-analysis of the EPIC 220522664 (K2-149) system and determined that there are probably six Super-Earths around this star. However, I would like a second opinion on my results, as I think I might be overestimating some of the planets' radii due to stellar noise interference, and I'm not particularly confident about the final two candidates. My results can be found here: https://www.zooniverse.org/projects/ianc2/exoplanet-explorers/talk/821/456532?comment=1302189&page=2

    I used the EVEREST light curve with filters 20, 21, 23, 24, 25, and 27 checked, and detrended it to fitting level 16. The first four planets can be found with the BLS algorithm, while the final two were found though manual transit hunting. These are the signals I used:

    null PlanetaryTransit 1 EPIC-220522664.05 2566.117297 2566.301185 37.226523000000 1080

    null PlanetaryTransit 1 EPIC-220522664.06 2564.676841 2564.860727 69.743461000000 837
