Korea Microlensing Telescope Network Microlensing Events from 2015: Event-finding Algorithm, Vetting, and Photometry
Dong-Jin Kim,Hyoun-Woo Kim,K. H. Hwang,Michael D. Albrow,S. J. Chung,Andrew Gould,Andrew Gould,Andrew Gould,C. Han,Y. K. Jung,Yoon-Hyun Ryu,In-Gu Shin,Jennifer C. Yee,Wei Zhu,Sang-Mok Cha,Seung-Lee Kim,Chung-Uk Lee,D. J. Lee,Yongseok Lee,B. G. Park,R. W. Pogge +20 more
TL;DR: In this paper, the authors present microlensing events in the 2015 Korea Microlensing Telescope Network (KMTNet) data and their procedure for identifying these events using a novel "completed event" micro-lensing event-finder algorithm.
