The ExoClock project has been created with the aim of increasing the efficiency of the Ariel mission. It will achieve this by continuously monitoring and updating the ephemerides of Ariel candidates over an extended period, in order to produce a consistent catalogue of reliable and precise ephemerides. This work presents a homogenous catalogue of updated ephemerides for 450 planets, generated by the integration of $\sim$18000 data points from multiple sources. These sources include observations from ground-based telescopes (ExoClock network and ETD), mid-time values from the literature and light-curves from space telescopes (Kepler/K2 and TESS). With all the above, we manage to collect observations for half of the post-discovery years (median), with data that have a median uncertainty less than one minute. In comparison with literature, the ephemerides generated by the project are more precise and less biased. More than 40\% of the initial literature ephemerides had to be updated to reach the goals of the project, as they were either of low precision or drifting. Moreover, the integrated approach of the project enables both the monitoring of the majority of the Ariel candidates (95\%), and also the identification of missing data. The dedicated ExoClock network effectively supports this task by contributing additional observations when a gap in the data is identified. These results highlight the need for continuous monitoring to increase the observing coverage of the candidate planets. Finally, the extended observing coverage of planets allows us to detect trends (TTVs - Transit Timing Variations) for a sample of 19 planets. All products, data, and codes used in this work are open and accessible to the wider scientific community.

V1298 Tau with TESS: Updated Ephemerides, Radii, and Period Constraints from a Second Transit of V1298 Tau e
金牛座V1298是一颗年轻的K型恒星，拥有四颗大小介于0.5 - 0.9 $R_J$之间的凌日系外行星。考虑到该系统的年轻，它提供了一个独特的机会来了解行星半径在同一恒星环境中不同距离的演变。V1298 Tau最初于6年前在K2 Campaign 4期间被观测到。现在，V1298 Tau在美国宇航局的凌日系外行星调查卫星（TESS）的延长任务中被重新观察到。在这里，我们从10分钟的TESS全帧图像中对V1298 Tau进行了新的光度观测。我们使用TESS数据更新V1298 Tau bcd的星历表，并将新观察到的半径与从K2光变曲线测量的半径进行比较，在$1-2σ$水平上，在更红的TESS带通中发现V1298 Tau bcd的较浅的凌日。我们怀疑半径上的差异是由于星点交叉事件或来自附近与V1298 Tau相同像素的暗淡恒星的污染。此外，我们赶上了第二次过境V1298头e，并提出了一种新的方法来推导一个行星的周期从两个过境观察年的边缘后验概率。我们发现V1298 Tau e的最高概率周期与V1298 Tau b处于近2：1的平均运动共振，如果得到证实，可能使V1298 Tau bcde成为4行星共振链。V1298 Tau是几个正在进行和未来观测的目标。这些更新的星历表对于安排未来的过境观测和解释未来的多普勒层析成像或透射光谱信号至关重要。
