Adaptive data reduction workflows for astronomy: The ESO Data Processing System (EDPS) [PDF]
Astronomy & Astrophysics, 2023 Context. Astronomical data reduction is usually done via processing pipelines that consist of a series of individual processing steps that can be executed one at a time. These processing steps are then strung together into workflows and fed with data to address a particular processing goal.

Survey of Object-Based Data Reduction Techniques in Observational Astronomy
Open Physics, 2016 AbstractDealing with astronomical observations represents one of the most challenging areas of big data analytics. Besides huge variety of data types, dynamics related to continuous data flow from multiple sources, handling enormous volumes of data is essential.

Principles of the data reduction and first results of the fastscanning method for (sub)millimeter astronomy [PDF]
Astronomy & Astrophysics, 2002 Ground-based astronomical continuum observations at (sub)millimeter wavelengths are especially difficult, because the emission of the atmospheric water vapor is usually much stronger than any astronomical signal. We present here the principles of the data reduction and first results of a new observing method that accounts for the atmospheric emission ...

Automatic model-based telluric correction for the ESPRESSO data reduction software. Model description and application to radial velocity computation [PDF]
Astronomy & Astrophysics, 2022 Ground-based high-resolution spectrographs are key instruments for several astrophysical domains. Unfortunately, the observed spectra are contaminated by the Earth's atmosphere.

Automatic spectroscopic data reduction using BANZAI [PDF]
Astronomical Telescopes + Instrumentation, 2022 Time domain astronomy has both increased the data volume and the urgency of data reduction in recent years. Spectra provide key insights into astrophysical phenomena but require complex reductions.

A Model Estimator for Noisy Compact Emission Recovery in Radio Synthesis Imaging
The Astronomical Journal, 2023 Reconstruction of a noisy compact emission must consider not only the point-spread function but also the effect of noise. However, the traditional threshold method in widely-used CLEAN-based algorithms finds it difficult to effectively prevent noise in ...
