cds-question@unistra.frexoplanetsastronomical-reference-materialsThe ExoClock project is an inclusive, integrated, and interactive platform that was developed to monitor the ephemerides of the Ariel targets to increase the mission efficiency. The project makes the best use of all available resources, i.e., observations from ground telescopes, midtime values from the literature, and finally, observations from space instruments. Currently, the ExoClock network includes 280 participants with telescopes capable of observing 85% of the currently known Ariel candidate targets. This work includes the results of ~1600 observations obtained up to 2020 December 31 from the ExoClock network. These data in combination with ~2350 midtime values collected from the literature are used to update the ephemerides of 180 planets. The analysis shows that 40% of the updated ephemerides will have an impact on future scheduling as either they have a significantly improved precision or they have revealed biases in the old ephemerides. With the new observations, the observing coverage and rate for half of the planets in the sample has been doubled or more. Finally, from a population perspective, we identify that the differences in the 2028 predictions between the old and the new ephemerides have an STD that is double what is expected from Gaussian uncertainties. These findings have implications for planning future observations, where we will need to account for drifts potentially greater than the prediction uncertainties. The updated ephemerides are open and accessible to the wider exoplanet community both from our Open Science Framework repository and our website.2022ApJS..258...40Khttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJS/258/40CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+A/507/481 : GJ 436b and XO-1b transits (Caceres+, 2009)J/ApJ/704/1107 : Transiting planets in HATNet field 205 (Latham+, 2009)J/A+A/508/1011 : Planetary transit of TrES-1 and TrES-2 (Rabus+, 2009)J/ApJ/691/1145 : Spectrophotometry of TrES-3 and TrES-4 (Sozzetti+, 2009)J/MNRAS/408/1494 : Planetary transits of TrES-2 and TrES-3 (Colon+, 2010)J/A+A/524/A25 : Radial Velocities on 6 exoplanet host stars (Triaud+, 2010)J/ApJ/742/116 : Photometry of 4 massive exoplanets (Bakos+, 2011)J/ApJ/733/116 : HAT-P-28 and HAT-P-29 photometry (Buchhave+, 2011)J/AJ/141/179 : Transits of TrES-4b, HAT-P-3b and WASP-12b (Chan+, 2011)J/ApJ/726/52 : HAT-P-18 and HAT-P-19 follow-up (Hartman+, 2011)J/ApJ/742/59 : HAT-P-32 and HAT-P-33 follow-up (Hartman+, 2011)J/A+A/527/A85 : Light curves of HAT-P-3b and HAT-P-14b (Nascimbeni+, 2011)J/AJ/141/63 : Relative RVs of HAT-P-4 & HAT-P-14 (Winn+, 2011)J/MNRAS/422/1988 : Three short-period, transiting exoplanets (Anderson+, 2012)J/AJ/144/19 : Follow-up phot. for HAT-P-34, -35, -36 & -37 (Bakos+, 2012)J/AJ/144/139 : HAT-P-39, HAT-P-40, and HAT-P-41 follow-up (Hartman+, 2012)J/MNRAS/426/739 : Velocities for 7 transiting hot Jupiters (Hellier+, 2012)J/A+A/544/A72 : WASP-42 & WASP-49 photometry and velocities (Lendl+, 2012)J/A+A/547/A61 : WASP78 and WASP79 RV and photometric data (Smalley+, 2012)J/A+A/557/A30 : Transits of HAT-P-16 and WASP-21 (Ciceri+, 2013)J/A+A/551/A73 : RVs for WASP-54b, WASP-56b and WASP-57b (Faedi+ 2013)J/A+A/552/A82 : WASP-64b and WASP-72b light curves (Gillon+, 2013)J/A+A/559/A36 : Exoplanets WASP-65b and WASP-75b (Gomez Maqueo Chew+, 2013)J/A+A/549/A134 : 4 new WASP close-in giant planets (Hebrard+, 2013)J/MNRAS/434/1300 : WASP-15 and WASP-16 light curves (Southworth+, 2013)J/MNRAS/445/1114 : WASP-69b, WASP-70Ab and WASP-84b (Anderson+, 2014)J/A+A/563/A143 : WASP-68b, WASP-73b, WASP-88b transits (Delrez+, 2014)J/AJ/147/128 : HAT-P-44, HAT-P-45, and HAT-P-46 follow-up (Hartman+, 2014)J/A+A/570/A64 : WASP-104b and WASP-106b photometry (Smith+, 2014)J/MNRAS/444/776 : Transiting planets WASP-24, 25 and 26 (Southworth+, 2014)J/A+A/575/A61 : WASP-20b and WASP-28b photometry and RV (Anderson+, 2015)J/A+A/577/A54 : HAT-P23 and WASP-48 light curves (Ciceri+, 2015)J/AJ/150/168 : Sp. & phot. for HAT-P-50--HAT-P-53 (Hartman+, 2015)J/A+A/579/A136 : HAT-P-36 and WASP-11/HAT-P-10 light curves (Mancini+, 2015)J/A+A/580/A63 : HATS-13b and HATS-14b light and RV curves (Mancini+, 2015)J/AJ/152/161 : Photometry for HATS-31--HATS-35 (de Val-Borro+, 2016)J/AJ/152/108 : i-band phot. for HATS-25 through HATS-30 (Espinoza+, 2016)J/AJ/152/182 : iz follow-up phot. of HAT-P-65 & HAT-P-66 (Hartman+, 2016)J/ApJS/225/9 : Kepler TTVs.
