Feature request: astroquery splatalogue filter to show astronomically observed transitions

Hi there,

Just wanted to see if it’s possible to add an option to the Splatalogue query to only show astronomically observed transitions. Since there’s already the option to only show NRAO recommended transitions, maybe it’s simple to implement.

They have this search filter on their website (circled in red in picture below).

Not sure if it’s in the future plan already, so I thought I can at least ask! Thank you!

The issue names the Splatalogue query and the existing NRAO recommended-transitions option, but no repository files or tests. Start by locating that query implementation and checking how the website's astronomically observed filter is represented; done means exposing an option that returns only astronomically observed transitions and adding coverage for it.
