The Gemini Near-infrared Integral Field Spectrograph (NIFS) reduction pipeline is widely used to reduce NIFS data. However, there are critical known limitations. A new NIFS reduction pipeline has recently been developed and solves several of these problems. We present a comparison of stellar kinematics derived from the new and old data reduction pipelines, as well as recommendations for optimal NIFS data reduction.

来自两个 Gemini NIFS 减少管道的恒星运动学比较

Gemini 近红外积分场光谱仪 (NIFS) 缩减管道广泛用于缩减 NIFS 数据。但是，存在一些重要的已知限制。最近开发了一种新的 NIFS 减少管道，并解决了其中的几个问题。我们比较了从新旧数据缩减管道派生的恒星运动学，以及最佳 NIFS 数据缩减的建议。
