The main thrust of this 1-year project is to debug and optimize the existent codes that are used to process data from the Imaging Vector Magnetograph (IVM) gathered during 1992-2006 (1.5 solar cycles). Historic data from the IVM have contributed to major advances in understanding the photospheric vector magnetic fields of active regions on the Sun. The main goal is to advance those data-processing codes of IVM data, so that the released archive of IVM data is of as high quality as possible for use by the broad solar community. Upon completion of this project, the available IVM data archive will be treated consistently, and it will ready for scientific analysis. This research project will contribute to improved community knowledge on handling imaging spectro-polarimetric data, which will have an impact on analyzing data from the future DKIST (formerly known as the ATST). The project supports the Strategic Goals of the AGS Division in discovery, learning, diversity, and interdisciplinary research. A consistently produced archive of IVM data presents a unique data source for studying the long-term behavior of the Sun, since it allows for inversion-independent determination of magnetic field strengths in sunspots over 1.5 solar cycles. The IVM data have featured prominently in novel investigations of solar flares and their prediction --- a topic with societal impacts that range from communications disruptions to power-grid outages. The IVM data would contribute to the large statistical samples needed for further progress, complementing present data from SDO/HMI. Predicting solar flares, and quantitatively understanding the inter-cycle behavior of our Sun, are questions with potentially major impacts on today's society.

这个为期一年的项目的主要目的是调试和优化现有的代码，这些代码用于处理1992 - 2006年期间收集的成像矢量磁力仪（IVM）的数据（1.5太阳能循环）。 来自IVM的历史数据在理解太阳上活跃区域的光电矢量磁场方面有了重大进展。 主要目的是推进IVM数据的数据处理代码，以便发布的IVM数据档案量尽可能高，以供广阔的太阳能社区使用。 该项目完成后，可用的IVM数据档案将得到一致的处理，并准备好进行科学分析。 该研究项目将有助于提高社区知识，以处理成像光谱极光数据，这将影响分析未来DKIST（以前称为ATST）的数据。 该项目支持AGS部门在发现，学习，多样性和跨学科研究方面的战略目标。 始终产生的IVM数据存档介绍了一个独特的数据源，用于研究太阳的长期行为，因为它允许非倒置与超过1.5太阳能周期的黑子中磁场强度的确定。 IVM数据在对太阳耀斑及其预测的新颖调查中突出了，这是一个具有社会影响的话题，范围从通信破坏到电网中断。 IVM数据将有助于进一步进展所需的大型统计样本，并补充SDO/HMI的当前数据。 预测太阳耀斑，并定量理解我们的太阳的周期间行为，是对当今社会产生重大影响的问题。
