Simultaneous PSF Matching via Dual Kernel Optimization
Carter Lee Rhea, Pieter Van Dokkum, Roberto Abraham +6
Standard point spread function (PSF) matching algorithms consider one image as the reference and aim to find a convolution kernel such that, when applied to the reference image, th…
dfcosmic: A Python package for cosmic ray removal
Carter Lee Rhea, Pieter van Dokkum, Steven R. Janssens +5
Astronomical images often show sharp features that are caused by cosmic ray (CR) hits, hot pixels, or non-Gaussian noise. L.A.Cosmic (van Dokkum 2001) is a widely used edge detecti…
dfreproject: A Python package for astronomical reprojection
Carter Lee Rhea, Pieter Van Dokkum, Steven R. Janssens +5
Deep astronomical images are often constructed by digitially stacking many individual sub-exposures. Each sub-exposure is expected to show small differences in the positions of sta…
A Recipe for Unbiased Background Modeling in Deep Wide-Field Astronomical Images
Qing Liu, Roberto G. Abraham, Peter G. Martin +9
Unbiased sky background modeling is crucial for the analysis of deep wide-field images, but it remains a major challenge in low surface brightness astronomy. Traditional image proc…
