摘要:

ADITYA L-1是印度第一个专门研究太阳及其大气层的飞行任务,其可见光发射线日冕仪(VELC)是ADITYA-L1的主要有效载荷。VELC可以同时对日冕进行成像和光谱观测。将在500 nm处连续成像,视场(FOV)为1.05 Ro至3Ro。在1.05-1.5Ro的视场范围内,将对日冕进行5303 [Fe XIV]、7892 [Fe XI]、10747 [Fe XIII]三条发射线的光谱观测和10747 [Fe XIII]的分光偏振测量。在这项工作中,端到端的数据管道架构和开发的VELC有效载荷。讨论了VELC提案提交表、卫星观测参数、数据产品、级别定义、数据管道和分析软件,以将使用卫星上VELC仪器获得的大量原始数据集处理为科学可用数据。

英文摘要:

ADITYA L-1 is India's first dedicated mission to study Sun and its atmosphere with Visible Emission Line Coronagraph (VELC), a major payload on ADITYA-L1. VELC has provision to make imaging and spectroscopic observations of the corona, simultaneously. Imaging with the Field of View (FOV) from 1.05Ro to 3Ro will be done in continuum at 500nm. The spectroscopic observations of solar corona in three emission lines, namely 5303 Å [Fe XIV], 7892 Å [Fe XI], 10747 Å [Fe XIII], and Spectro-polarimetry at 10747 Å [Fe XIII] will be performed with FOV of 1.05-1.5Ro. In this work, the end-to-end data pipeline architecture and development of the VELC payload are presented. The VELC proposal submission form, satellite observation parameters, data products, level definitions, data pipeline and analysis software to process the big raw data sets obtained using VELC instruments onboard satellite to science-ready data are discussed.
