'Documentation on TABLES and __TABLES_SUMMARY__ and other double underscore metadata (bigquery)

I'm diving into metadata available on datasets and tables in BigQuery.

There is enough documentation on INFORMATION_SCHEMA:
https://cloud.google.com/bigquery/docs/information-schema-intro

But I can't find any on __TABLES__, __TABLES_SUMMARY__.
Where can I find information on this?
Are there any other double underscore functions like that?

What I'm using until now:

select * from `<project>.<dataset>.__TABLES__`
select * from `<project>.<dataset>.__TABLES_SUMMARY__`

__TABLES__ and __TABLES_SUMMARY__ is officially removed from Google BigQuery documentation and is not further in use. It was replaced with INFORMATION_SCHEMA.TABLES on May 2021.

Henceforth, to get the metadata of the tables it is advised to use INFORMATION_SCHEMA.TABLES. For reference as you mentioned this documentation is followed.
