在ESTERO项目中，正在建立一个新的灵活的数据简化库。ESTERO，岩石系外行星和稳定光谱观测的阶梯光栅光谱仪是一台光纤馈电，高分辨率，交叉分散的阶梯光栅光谱仪。其主要科学目标之一是使用径向速度技术搜索类地系外行星。正在开发一个专用管道。它被设计为能够减少来自不同的类似光谱仪的数据：不仅是ESTERO，而且还有HARPS，HARPS-N和其他可能的光谱仪。仪器细节可通过输入静态配置表进行配置。第一次编写的配方已经测试HARPS和HARPS-N真实的数据和ESTERO模拟数据。管道的最终科学产品将是提取的一维和二维光谱。利用这些产品，可以高精度地计算被观测物体的径向速度。该库在标准ESO管道环境中开发。它是用ANSI C编写的，并使用了通用管道库（CPL）。它可以以通常的方式与ESO工具Esorex，Gasgano和Reflex结合使用。
Within the ESPRESSO project a new flexible data reduction library is being built. ESPRESSO, the Echelle SPectrograph for Rocky Exoplanets and Stable Spectral Observations is a fiber-fed, high-resolution, cross-dispersed echelle spectrograph. One of its main scientific goals is to search for terrestrial exoplanets using the radial velocity technique. A dedicated pipeline is being developed. It is designed to be able to reduce data from different similar spectrographs: not only ESPRESSO, but also HARPS, HARPS-N and possibly others. Instrument specifics are configurable through an input static configuration table. The first written recipes are already tested on HARPS and HARPS-N real data and ESPRESSO simulated data. The final scientific products of the pipeline will be the extracted 1-dim and 2-dim spectra. Using these products the radial velocity of the observed object can be computed with high accuracy. The library is developed within the standard ESO pipeline environment. It is being written in ANSI C and makes use of the Common Pipeline Library (CPL). It can be used in conjunction with the ESO tools Esorex, Gasgano and Reflex in the usual way.
