What was the name of the Slavic Pantheon?

As far as I know the only name for the Pantheon was Svarozhichs, for which I'm not sure if it's authentic.

I also found an interesting deity from Poland which was named Jesza/Yesza. Some say it was just a name for the highest god in the Slavic Pantheon, and could be the equivalent of the Roman "Jupiter". It looks like someone mentioned that the name could be related to PIE word *ansu- ("lord, ruler, god") like: Celtic "Esus", Norse "Aesir", Zoroastrian "Ahura" and Sanskrit "Asura".

I think it would be a cool name for Slavic Pantheon to be called Jeszas/Yeszas if we could relate these names. But if there are some old mentions of the name for the Slavic Pantheon, I would like to hear more about it.
