my mistake then, I didn’t see OP’s claim when I clicked his profile earlier, & after googling it does seem like he is Petr Soural, but astro-seek is still a website that’s been used in the astrology community for years, has many different developers, creators & contributors associated with it (with at least five beside himself listed on the contact page) & one of its features is still astrological mapping - which is essentially the same thing as establishing an ephemerides database; it’s the same data, it’s just being used for a different purpose, & it still isn’t a ‘grift’. you’re dismissing something you don’t know anything about, making assumptions because ‘astrology’ & saying it doesn’t belong here, despite it being mathematical data, & that’s what I was trying to point out. it’s literally data & it’s literally beautiful.

eta - genuine question, would any other programmer or developer be discouraged from sharing their datasets here?

by grifting website do you mean the astrological mapping website that was used to calculate this data & is not owned by OP in any way, shape or form?
