Ladies, Gentlemen, please let me report you (IERS snob my messages) something strange. Despite their name (International EARTH ROTATION Service), they do <del>not</del> (<ins>actually they do as Δω<sub>3</sub>, I apologize</ins>) publish in their proper [https://hpiers.obspm.fr/eop-pc/index.php?index=C04&lang=en page] data and plots for EARTH ROTATION speed (omega). Though omega is UT1's independent variable according to Newcomb's formula (omega replaces sidereal time), UT1-UTC depends on two speeds: omega and cesium atom's oscillation. <ins>It follows, monitoring UT1-UTC (or UT1-TAI) we do not monitor omega.</ins> With regards and friendship, Georges Theodosiou, The Straw Man [[User:Georges T.|Georges T.]] ([[User talk:Georges T.|talk]]) 07:25, 29 September 2021 (UTC) 09:50, 27 April 2022 (UTC)

Ladies, Gentlemen, please let me tell you interesting facts regarding IERS's monitoring of Earth's omega. At IERS/EOC's [https://hpiers.obspm.fr/eop-pc/index.php front page] the plot depicts LOD as having equal value in the middle of the year and a year earlier. In the [https://hpiers.obspm.fr/eop-pc/products/combined/C04plottest.php?date=2&dimx=1200&dimy=900&tver=1&graphe=5&year1=2021&month1=8&day1=1&year2=2031&month2=12&day2=31&langue=1&SUBMIT=Submit+request IERS/EOC] and [https://maia.usno.navy.mil/information/plots IERS/RS-PC] (last plot) charts, the zigzags in the middle of the 2023 and 2022 should be at the same height if it were true, but they are not. On the other hand, if you click on their Vondrak filter chart, a back page appears. It is slightly different from the front one and might be accurate. The curve at midyear is still higher than the curve at midyear 2022. By the way, I should mention that I used a paraphrasing tool this time. Please offer your opinion.
