Globular Cluster M4 variables light curves

M4 cluster was observed in 2011 by 2 telescopes of WISE Observatory, Tel Aviv University, Israel - C18 and T40, from April till July. This dataset contains the light curves for the new and known variables as described in the paper: Safonova et al. Search for Low-mass Objects in the Globular Cluster M4. I: Detection of Variable Stars. 2016, Astronomical Journal. The name of the variable is in the name of the light curve, and the name of the telescope is given in the beginn ing of the name, such as: c18V33R_lc.dat --- c18 - means the 18" telescope C18, V33 - is the name of the variable, capital R - means standard R mag. t40 - means 40" (1-m) telescope T40, Small 'r' or 'i' mean that the magnitudes are instrumental.

2011年4月至7月，以色列特拉维夫大学WISE天文台的两台望远镜C18与T40对M4球状星团开展了观测。本数据集包含新发现与已报道变星（variable stars）的光变曲线（light curves），相关细节详见论文：Safonova等人《球状星团M4中低质量天体搜寻：I. 变星探测》，2016年《天文期刊（Astronomical Journal）》。光变曲线的文件名中包含变星名称，且文件名开头标注了所用望远镜：例如c18V33R_lc.dat，其中c18代表18英寸望远镜C18，V33为变星编号，大写R表示标准R波段星等；t40代表40英寸（1米）望远镜T40，小写r或i则表示该星等为仪器星等（instrumental magnitudes）。
