Data for: Fluctuation-theorem method of measuring a particle's mass without knowing its shape or density

All the time-series data of the particle positions used in the demonstration experiment are provided in .txt files. There are 69 files, one for each particle. The data are in three columns: time (seconds), x-position (meters), y-position (meters). The zero coordinate for (x,y) corresponds to the top-left corner of the camera's field of view, while (0.00973, -0.00608) is the bottom-right corner.本演示实验中使用的所有粒子位置时序数据均以.txt格式纯文本文件提供，共计69个文件，每个粒子对应一个独立文件。 数据包含三列信息，依次为时间（单位：秒）、x轴位置（单位：米）与y轴位置（单位：米）。该坐标系的(0,0)原点对应相机视场的左上角，而(0.00973, -0.00608)则对应该视场的右下角。
