Fast Globally Optimal Catalog Matching using MIQCP
The Astronomical Journal, 2023 We propose a novel exact method to solve the probabilistic catalog matching problem faster than previously possible. Our new approach uses mixed integer programming and introduces quadratic constraints to shrink the problem by multiple orders of ...

A Survey of the use of Astronomical Methods at Sea [PDF]
Journal of Navigation, 1966 This investigation of methods used in Astronomical Navigation has been carried out by means of questionnaires completed by senior students at a few of our Navigation Schools. The data has been classified into fairly broad categories since some of it has been rather difficult to assess, due to incomplete information on such details as trading areas ...

On a Method of reproducing Astronomical Photographs [PDF]
Nature, 1897 PROF. MAX WOLF, in his excellent article on the “Reflector and Portrait Lens in Celestial Photography,” published in your issue of April 22 last, mentions a method of “reproducing nebulous masses” from original negatives, and refers to my reproduction of a photograph of the nebula M. 8, done in collaboration with Mr. Lunt.

Correcting For Telluric Absorption: Methods, Case Studies, And Release Of The TelFit Code [PDF]
, 2014 Ground-based astronomical spectra are contaminated by the Earth's atmosphere to varying degrees in all spectral regions. We present a Python code that can accurately fit a model to the telluric absorption spectrum present in astronomical data, with ...

Comparison of Outlier Detection Methods on Astronomical Image Data [PDF]
, 2021 Among the many challenges posed by the huge data volumes produced by the new generation of astronomical instruments there is also the search for rare and peculiar objects. Unsupervised outlier detection algorithms may provide a viable solution. In this work we compare the performances of six methods: the Local Outlier Factor, Isolation Forest, k-means ...
