Errors for the isophotal positions #446

Closed mkuemmel closed 2 years ago

mkuemmel commented 2 years ago

pixel_centroid_x/y and consequently world_centroid_alpha/delta don't have errors right now.

Would be good to have them.

The quantities implemented in #417 compute the variance on the pixel_centroid_x/y.

That ellipse needs to be translated to world coordinates for world_centroid_alpha/delta. But SE2 does not have this, so there is no urgency to implement this.
