And what another website reports: 

The script you have provides observation points, right? So from there you can get pixels for given times of interest.

yes, approximately. You may want to compute some more times in between, a swath is usually more rounded (I'm assuming the satellite goes horizontally in this image)

A you can see in the previous script, the points compute across track are `scan_points = np.arange(24, 2048, 40)` if you want just the edges, set `scan_points = np.array([0, 2047])`...

This is unfortunately not enough information to do that. You need to know the scan pattern (sweep, push broom, circular, etc), the scanning angles for each pixel (or at least...

yes, that's the question! you need to find a technical description of the instrument that gives you the angle values for the IFOV and FOV

@simonrp84 can you produce a minimal example that exhibits the error without relying on a data file? That way we would have something to test against.

@epsg Thanks a lot for putting this all together! I haven't looked at the code yet, but it sounds great! 1. regarding limits, I would issue a warning after 3...

Ok, a lot of good things here, thanks a lot for taking this up again! So I had a good look at the code, and the principles are sound. I...

@adybbroe Any insight ?
