VizieR Online Data Catalog: Eclipsing binary search in QUEST (Cuevas-Otahola+, 2019)

In this work, we make use of the QUEST variability survey at low Galactic latitude from Mateu et al. (2012MNRAS.427.3374M, Cat. J/MNRAS/427/3374). This catalogue spans a total area of 476deg² with 6513705 point sources and consists of multi-epoch observations in the VRI filters obtained fully with the Jurgen Stock Schmidt telescope and the QUEST-I camera (Baltay et al. 2002PASP..114..780B) at the National Astronomical Observatory in Llano del Hato, Merida, Venezuela. The observations correspond to a low Galactic latitude zone in the range -25°~<b~<30° approximately in direction towards the Galactic anticentre 190°=<l=<230°. The time sampling of the survey is quite inhomogeneous as it comprises observations from many different projects with different scientific goals, and spans observations obtained between 1998 November and 2006 June.

To characterize the completeness of the variable stars identification, we use ellisa to generate a mock catalogue to mimic the time sampling and photometric errors of the QUEST survey.

The goal of the ELLISA simulator is to generate a library of synthetic multifilter light curves for a population of eclipsing binaries, reproducing the time sampling and photometric errors representative of the survey the user wants to simulate. This makes it possible to generate a synthetic library that mimics the way we would observe a population of eclipsing binaries with an arbitrary instrument and time sampling. ELLISA is made publicly available as a python stand-alone code and library at a GitHub repository (https://github.com/umbramortem/ELLISA).
