Product Information: 8.50" by 11.00", 165 pages, softbound, (see below for magnetic versions).

The tables and computer programs detailed in Planetary
Programs and Tables From -4000 to +2800 allow the computation of the positions of the Sun, and 7 planets with a precision better than 0.01 degree over the period -4000, +2000 for Mercury, Venus, Mars, Jupiter and Saturn and +1600 to +2800 for Uranus and Neptune.

Until now, the astronomical tables covering large historic and prehistoric periods give the geocentric positions of the planets for equidistant dates. As an example, the tables of B. Tuckerman give the positions of the Sun and planets at 5-(Mercury, Venus) or 10-day (Sun, Mars, Jupiter and Saturn) intervals over the -600 to +1649. Coordinates are the longitude of the Sun, the geocentric longitudes and the geocentric latitudes of the planets. Such tables, over the entire period from -4000 to +2600 would include over 3,700,000 numbers and would constitute a 3,000 page book.

Instead, compact tables and simple computations of the Sun and planets on a small computer are described in this book. Time-dependent expansions of the longitude and radius vector of the Sun as well as the heliocentric coordinates of the planets are provided. These coordinates refer to the mean equinox and ecliptic of date.

For the Sun, Mercury, Venus and Mars each coordinate is represented in Planetary Programs and Tables From -4000 to +2800 by only by one formula provided for the entire period -4000 to +2600. This formula includes between 5 and 60 terms depending on the coordinate and planet.

For Jupiter, Saturn, Uranus and Neptune the coordinates are expressed for time-spans of five years by power series with seven coefficients. The period -4000, +2600 is then constituted by 1320 time-spans of five years. In addition to the tables, formulae for corrections of aberration and nutation which allow you to compute apparent geocentric coordinates are provided.

Windows OS only, Software Sketchy but works. Use with precautions and do a security scan afterwards.
Ok, I was really annoyed when I found out this waste ink pad causes the printer to be "end of life." I currently have the ET2800, and after 15,500 pages, I got this message. I own a small stationery business, which is why I print a lot. However, I used to work on large multi-function printers that had user-replaceable waste ink cartridges. I called Epson in hopes that they would just send me the part and be done with it. BUT NOPE, they wanted me to send in pictures, then I had to either send the printer in or get a certified technician to work on it. I looked online and found this, along with several videos on how a regular user can replace it themselves. It was easy, with no issues. You do need to physically plug the printer into your computer. OH, and the SOFTWARE is only compatible ON WINDOWS; it does not work on MAC OS and GOOGLE OS. Just FYI. The only problem I had was that the software, which is usually offered by third-party products from Amazon, has a sketchy website attached to it. BUT this was the best one to use because you DO NOT NEED A KEY to reset the waste ink counter. You simply use their application, and that's it. One tip I suggest is to uninstall or delete the application and its folder after you have finished resetting. Also, empty your recycle bin. Then run a quick Windows security scan.

Might Need to Turn Off Security Measures in Order to Download
I'm a 1st grade teacher and use my ET-2800 religiously. We own 4 of them, between home, my husband's and my classroom, and one for sublimation. I've printed over 15,000 copies on my school printer in the last few years and had no idea about the ink pad replacement until the error message popped up and wouldn't work anymore. I originally purchased a different set and couldn't get it to work. I was in panic mode so I ordered this set, which also originally didn't work. After really paying attention to the alerts that were popping up, I finally had to Google how to turn off my McAfee and Windows Security programs. They were blocking it from running. Once I did that, it was able to install and it is back up and running again. It did make me very nervous to turn them off but as soon as I got it installed, I turned them right back on and ran scans. So far I haven't had any issues in the last few days. The installation is extremely easy, it came with gloves, a screw driver, etc. Mine wasn't messy, so I didn't need the gloves or anything. It's also a 3-pack, so I left myself reminders for next time on how turn off the security. If you are having installation problems, turn off all of your malware security and that will probably help. Just make sure you turn it back on and run scans, the whole process with all of these websites seems shady and scary at first, but this one appears to be legit. I did read that Windows 10 and 11 tend to block sites that are deemed safe.
