FluxCT: A Web Tool for Identifying Contaminating Flux in Kepler and TESS Target Pixel Files
arXiv:2302.10189 · doi:10.3847/2515-5172/acb936
Abstract
We announce FluxCT, a web tool for identifying contaminating flux in Kepler and TESS target pixel files due to secondary visual sources. We demonstrate the usage of this tool and discuss the benefits of this tool over a simple Gaia radius search. FluxCT focuses on clarity and simplicity, where the only input needed from the user is a KIC or TIC ID. By more appropriately accounting for the actual shape of the photometric pixel apertures, FluxCT can produce much more accurate estimates of contaminating flux than simple radial cone searches.
