Geodetic or geocentric?

Afaik, the latitude of a place on Earth usually used in astronomy (solar
eclipse, occultations, apparent coordinates of a planet, ...) or, generally
speaking, in the atlas, is the geodetic latitude (aka geographic) and not
the geocentric latitude.
To better understand what I mean, you can see:

Could anybody confirm that?

Thanks

Correct. Quoted latitudes are always geodetic. Conversion to geocentric,
to perform parallax or velocity calculations, is straightforward - simple
formulas. Geocentric to geodetic is a bit harder.
