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…
Realizing the potential of the Dragonfly Spectral Line Mapper: Calibration methods and on-sky performance
Deborah M. Lokhorst, Seery Chen, Imad Pasha +8
The Dragonfly Spectral Line Mapper is an innovative all-refracting telescope designed to carry out ultra-low surface brightness wide-field mapping of visible wavelength line emissi…
Software infrastructure for the highly-distributed semi-autonomous Dragonfly Spectral Line Mapper
Imad Pasha, Seery Chen, Deborah Lokhorst +6
The Dragonfly Spectral Line Mapper (DSLM) is a semi-autonomous, distributed-aperture based telescope design, featuring a modular setup of 120 Canon telephoto lenses, and equal numb…
The Dragonfly Spectral Line Mapper: Completion of the 120-lens array
Seery Chen, Deborah M. Lokhorst, Imad Pasha +7
The Dragonfly Spectral Line Mapper is a mosaic telescope comprising 120 Canon telephoto lenses, based on the design of the Dragonfly Telephoto Array. With a wide field of view, and…
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…
