The LSST Science Pipelines Software: Optical Survey Pipeline Reduction and Analysis Environment
Rubin Observatory Science Pipelines Developers, Yusra AlSayyad, Robert Armstrong +83
The NSF-DOE Vera C. Rubin Observatory is executing the Legacy Survey of Space and Time (LSST) as its prime mission, producing a series of data releases over the ten-year survey. Th…
An overview of stray light findings and interpretation during on-sky commissioning of LSSTCam
Gabriele Rodeghiero, Alex Drlica-Wagner, Alessio Taranto +78
Wide-field telescopes are intrinsically difficult to shield from unwanted stray and scattered light, while the search to identify sources of contaminating light is frequently a cha…
Investigation and Mitigation of a Prominent Off-Axis Stray Light Path in Rubin Observatory Commissioning
Alex Drlica-Wagner, Alessio Taranto, Gabriele Rodeghiero +12
The "scratched tape" stray light feature is the most prominent and prevalent stray light artifact identified during the commissioning of the Vera C. Rubin Observatory. The scratche…
In Situ Measurements of the Reflectances of the LSSTCam Optics and Assessing the Impact of Optical Ghosts
Aashay Pai, Alex Drlica-Wagner, Lee S. Kelvin +4
Optical ghosts are image artifacts caused by successive reflections of light between optical surfaces such as lenses, filters, and detectors. These artifacts are unavoidable due to…
Modeling of the diffuse background produced by the Vera C. Rubin Observatory M2 baffle scattered light
Alessio Taranto, Gabriele Rodeghiero, Luca Rosignoli +58
The Vera C. Rubin Observatory, with its unprecedented field of view and fast focal ratio, will survey the entire sky every 3.5 nights. This unique capacity requires dealing with of…
Photometric Redshift Estimation for Rubin Observatory Data Preview 1 with Redshift Assessment Infrastructure Layers (RAIL)
T. Zhang, E. Charles, J. F. Crenshaw +87
We present the first systematic analysis of photometric redshifts (photo-z) estimated from the Rubin Observatory Data Preview 1 (DP1) data taken with the Legacy Survey of Space and…
Bright Star Subtraction Pipeline for LSST: Phase one report
Amir E. Bazkiaei, Lee S. Kelvin, Sarah Brough +3
We present the phase one report of the Bright Star Subtraction (BSS) pipeline for the Vera C. Rubin Observatory's Legacy Survey of Space and Time (LSST). This pipeline is designed…
Bright Star Subtraction Pipeline for LSST: Progress Review
Amir E. Bazkiaei, Lee S. Kelvin, Sarah Brough +3
We present the Bright Star Subtraction (BSS) pipeline for the Vera C. Rubin Observatory's Legacy Survey of Space and Time (LSST). This pipeline generates an extended PSF model usin…
Sky Subtraction in an Era of Low Surface Brightness Astronomy
Lee S. Kelvin, Imran Hasan, J. Anthony Tyson
The Vera C. Rubin Observatory Wide-Fast Deep (WFD) sky survey will reach unprecedented surface brightness depths over tens of thousands of square degrees. Surface brightness photom…
Faro: A framework for measuring the scientific performance of petascale Rubin Observatory data products
Leanne P. Guy, Keith Bechtol, Jeffrey L. Carlin +14
The Vera C. Rubin Observatory will advance many areas of astronomy over the next decade with its unique wide-fast-deep multi-color imaging survey, the Legacy Survey of Space and Ti…
Galaxy And Mass Assembly (GAMA): autoz spectral redshift measurements, confidence and errors
I. K. Baldry, M. Alpaslan, A. E. Bauer +17
The Galaxy And Mass Assembly (GAMA) survey has obtained spectra of over 230000 targets using the Anglo-Australian Telescope. To homogenise the redshift measurements and improve the…
