Description

Feature Request

Is your feature request related to a problem? Please describe.

The parallax correction currently derives the satellite location from the metadata of the (cloud top) height dataset, either by orbital paramaters or by satellite name, datetime, and TLE. Some datasets may not include this information, which complicates using the parallax correction. It would be desirable if the user could explicitly pass the satellite location, so the parallax correction can still be used easily for datasets where this information is missing (or wrong).

Describe the solution you'd like

I would like that the parallax correction API is adapted to allow for explicit passing of satellite location.

Describe any changes to existing user workflow

There is no existing user workflow, because the parallax correction is brand new. It is also explicitly documented as experimental and subject to change.

Additional context

Alternately, the user would need to add the satellite location as CTH metadata before passing it for parallax correction. However, this could be complicated in practice.
