Teledyne H1RG、H2RG和H4RG噪声Generator
Teledyne H1RG, H2RG, and H4RG Noise Generator
摘要:
本文介绍了我们为詹姆斯韦伯太空望远镜(JWST)近红外光谱仪(NIRSpec)编写的近红外探测器系统噪声发生器(NG)。NG模拟许多重要的噪声分量,包括:(1)白色“读取噪声”,(2)残余偏置漂移,(3)粉红色$1/f$噪声,(4)交替列噪声,以及(5)图片帧噪声。通过调整输入参数,NG可以模拟Teledyne的H1 RG、H2 RG和H4 RG探测器的噪声,无论是否使用Teledyne的SIDECAR ASIC IR阵列控制器。NG可以作为模拟天文场景的起点,将暗电流、散射光和天文源添加到NG的结果中。NG是用Python-3.4编写的。源代码可以从http://jwst.nasa.gov/publications.html免费下载。
英文摘要:
This paper describes the near-infrared detector system noise generator (NG) that we wrote for the James Webb Space Telescope (JWST) Near Infrared Spectrograph (NIRSpec). NG simulates many important noise components including; (1) white "read noise," (2) residual bias drifts, (3) pink $1/f$ noise, (4) alternating column noise, and (5) picture frame noise. By adjusting the input parameters, NG can simulate noise for Teledyne's H1RG, H2RG, and H4RG detectors with and without Teledyne's SIDECAR ASIC IR array controller. NG can be used as a starting point for simulating astronomical scenes by adding dark current, scattered light, and astronomical sources into the results from NG. NG is written in Python-3.4.
