Nirmala,
Look at the words "Ephemeris" and "ephemerides" in the sources you provided on the previous page.
https://en.wikipedia.org/wiki/Ephemeris
Modern ephemerides are often computed electronically from mathematical models of the motion of astronomical objects and the Earth. Even though the calculation of these tables was one of the first applications of mechanical computers, printed ephemerides are still produced, as they are useful when computational devices are not available.
Yes, I get it that most of the data in these publications and on the timeanddate.com website are calculated. However, the links I offered explained that those calculations are based on observations taken over hundreds of years and the calculations are also refined when new technology allowed more accurate observations. Both the observations and calculations have proven reliable enough to have been used for those hundreds of years to navigate the oceans and less populated areas of the earth. If they were inaccurate, they would have been blamed by now for thousands if not hundreds of thousands of deaths over the centuries from shipwrecks and people lost in the wilderness. But instead the publications have been continuously published for 250 years and trusted by both navigators and astronomers who want to know when they can make their observations to avoid disasters at sea or when using extremely expensive telescopes where every minute of available time to make observations was and is considered too valuable to waste by looking in the wrong place at the wrong time. Computers have taken over for most applications from the paper publications, but the computations are the same ones used for centuries, and the results are accurate both when published on paper and when performed by a computer program.
I trust a collected body of knowledge (both observed and calculated) with that kind of track record, and yet you seem to not trust it, even when it also is used every day by people who simply need to know what time of the day it is somewhere else in the world, and/or what time of the day to head down to the beach to watch the sunset.
This is similar to our discussion about flight times. Airlines and air passengers all over the world trust the published schedules to give an accurate estimate of the time their flights will take, and the flightaware.com website collects and provides the actual flight data,,yet you seem to think there is no data. Although actually, I do not know what you think of the flightaware.com website I provided since you simply stopped participating on that thread. I did discover that if you simply register for free on their site, you can then access four months of recent flight data for any commercial flight that connects two airports on this planet based on the over 100,000 commercial flights completed each day. That all adds up to millions of data points documenting the times and therefore distances between those points with enough average accuracy to completely debunk all of the flat earth maps presented so far.
I don't know if you are suspicious of all outside information to an extreme degree, or if you simply feel threatened when there is overwhelming evidence that refutes your belief system. I also have considered that you simply post on here to see what kind of reaction you can get. You obviously do not owe me or anyone else an explanation, but I do find you unusually resistant to any evidence or even the invitation to conduct your own observations, including one that only requires you to step outside with a long straight stick. And yet, in another post, you offer to allow yourself to be sent up in a high altitude balloon and also promise to report back honestly on what you see. I have my own contradictions and hypocrisies to answer for in life, so I will leave you to yours.
