A Geometric Approach to Estimate Background in Astronomical Images
Estimating the true background in an astronomical image is fundamental to detecting faint sources. In a typical low-photon-count astronomical image, such as in the far- and near-ultraviolet wavelength ranges, conventional methods relying on 3 σ clipping and median or mode estimation often fail to ca...
