摘要:

双子座行星成像仪是一台新投入使用的设施仪器,旨在测量太阳附近年轻太阳系外行星的近红外光谱,并获得星周盘的成像偏振测量。GPI的科学仪器是一个积分场摄谱仪,它使用了带有SIDECAR ASIC读出系统的HAWAII-2 RG探测器。本文介绍了GPI数据简化管道执行的探测器表征和校准,以补偿包括坏/热/冷像素、持久性、非线性、振动引起的颤噪和相关读取噪声在内的影响。

英文摘要:

The Gemini Planet Imager is a newly commissioned facility instrument designed to measure the near-infrared spectra of young extrasolar planets in the solar neighborhood and obtain imaging polarimetry of circumstellar disks. GPI's science instrument is an integral field spectrograph that utilizes a HAWAII-2RG detector with a SIDECAR ASIC readout system. This paper describes the detector characterization and calibrations performed by the GPI Data Reduction Pipeline to compensate for effects including bad/hot/cold pixels, persistence, non-linearity, vibration induced microphonics and correlated read noise.
