A High-quality Velocity-delay Map of the Broad-line Region in NGC 5548

NGC 5548 has been well spectroscopically monitored for reverberation mapping of the central kinematics by 19 campaigns. Using the maximum entropy method in this Letter, we build up a high-quality velocity-delay map of the Hβ emission line in the light cur

通过19次观测活动，对NGC 5548进行了良好的光谱监测，以用于中心运动学的反响映射。在本文中，我们使用最大熵方法构建了光变曲线中Hβ发射线的高质量速度 - 延迟图。
