展开程序TRUEE是一个用于反问题数值解的软件包。该算法首次应用于FORTRAN 77程序RUN中。RUN是一种基于事件的展开算法，它利用了Tikhonov正则化。它已经被测试并与不同的展开应用程序进行了比较，并以非常稳定的结果和可靠的误差估计脱颖而出。TRUEE是一个从RUN到c++的转换，它在强大的ROOT框架内工作。该程序已被扩展为更加用户友好，并提供与RUN相同的展开结果。除了软件安装和图形生成的简单性之外，还有新的功能，可以方便用户选择展开参数和可观察对象。在本文中，我们介绍了新的展开程序，并通过将其分别应用于MAGIC望远镜和IceCube中微子探测器采集的两个天体粒子物理示例数据集来展示其性能。(c) 2012 Elsevier B.V.版权所有
The unfolding program TRUEE is a software package for the numerical solution of inverse problems. The algorithm was first applied in the FORTRAN 77 program RUN. RUN is an event-based unfolding algorithm which makes use of the Tikhonov regularization. It has been tested and compared to different unfolding applications and stood out with notably stable results and reliable error estimation. TRUEE is a conversion of RUN to C++, which works within the powerful ROOT framework. The program has been extended for more user-friendliness and delivers unfolding results which are identical to RUN. Beside the simplicity of the installation of the software and the generation of graphics, there are new functions, which facilitate the choice of unfolding parameters and observables for the user.In this paper, we introduce the new unfolding program and present its performance by applying it to two exemplary data sets from astroparticle physics, taken with the MAGIC telescopes and the IceCube neutrino detector, respectively.
