Catalogues and figures of the MSc thesis: Building the stellar calibrator catalogue for the Ariel mission

This dataset comprises the stellar calibrator catalogues and figures generated during the master's thesis project "Building the stellar calibrator catalogue for the Ariel mission" by Elena Tonucci (TU Delft, SRON). The four catalogues ("EChO list", "Catalogue 1", "Catalogue 2", and "Ariel Catalogue") are *.csv files comprising a list of stellar calibrator candidates with information on the stars including, for example, identifiers from different space missions, sky coordinates, stellar properties like mass, radius, effective temperature, magnitudes, metallicity, distance, quantities computed from the corresponding TESS light curves, and others. The purpose of these catalogues is to define a set of stable stellar calibrators to perform the in-flight flux calibration of ESA's Ariel mission. A *.zip folder comprises a figure (*.png) for each star in the so-called "Catalogue 2" showing a light curve time series of that star as observed by TESS, and the corresponding Lomb-Scargle Periodogram. These figures are helpful in displaying the flux variability of the stellar calibrator candidates.

本数据集收录了埃琳娜·托努奇（Elena Tonucci，代尔夫特理工大学（TU Delft）、SRON荷兰空间研究所）在其硕士学位论文课题《为Ariel任务（Ariel mission）构建恒星校准星表》期间生成的恒星校准星表与配套图表。本次研究共生成四份星表，分别为「EChO星表（EChO list）」、「星表1」、「星表2」与「Ariel星表（Ariel Catalogue）」，均为*.csv格式文件，收录了恒星校准候选天体列表，包含恒星的多维度信息，例如不同空间任务的天体标识符、天球坐标、恒星物理参数（质量、半径、有效温度、星等、金属丰度、距离等），以及由对应凌日系外行星巡天卫星（TESS）测光光变曲线计算得到的各类量化指标等。这些星表的核心用途是构建一套稳定的恒星校准源集合，用于完成欧洲空间局（ESA）Ariel任务的在轨通量校准工作。本数据集附带一个*.zip压缩包，其中包含「星表2」中每颗恒星对应的*.png格式图表，分别展示该恒星由TESS观测得到的光变曲线时序图，以及对应的隆-斯卡尔格勒周期图（Lomb-Scargle Periodogram）。此类图表可直观呈现候选校准恒星的通量变化特性。
