A Catalogue of Locus Algorithm Pointings for Optimal Differential Photometry for 23,779 Quasars
Oisín Creaner, Kevin Nolan, David Grennan +2
This paper presents a catalogue of optimised pointings for differential photometry of 23,779 quasars extracted from the Sloan Digital Sky Survey (SDSS) Catalogue and a score for ea…
The Locus Algorithm I: A technique for identifying optimised pointings for differential photometry
Oisín Creaner, Kevin Nolan, Eugene Hickey +1
Studies of the photometric variability of astronomical sources from ground-based telescopes must overcome atmospheric extinction effects. Differential photometry by reference to an…
The Locus Algorithm II: A robust software system to maximise the quality of fields of view for Differential Photometry
Kevin Nolan, Eugene Hickey, Oisín Creaner
We present the software system developed to implement the Locus Algorithm, a novel algorithm designed to maximise the performance of differential photometry systems by optimising t…
