@paulmueller thank you for looking into this.
Yes, I disabled weighting. I just wanted to report the behavior I found odd when I was testing this function out.
In the point 1., I understand that 180° must be covered for a proper reconstruction, unfortunately, this is not what you can measure in a real microscope. Case 2. makes sense, OK. Case 3. looks like a bug indeed. Might be just solved by raising an error, because I also can not imagine a case where somebody would actually have coverage >180°. Cheers

Maybe the docs could also be clearer about point 1.

I will try to explain what is happening:
-
It is assumed that a full 180° must be covered for a proper reconstruction. The idea is to give each angle a weight that is proportional to the distance to its neighboring angles. Obviously, this idea does not work if the angles are strongly unevenly distributed (e.g. dense coverage from 0° to 90°, nothing between 90° and 180°). But it works for the example cases in the docs. This basically answers the behavior in case (1).
-
For case (2), this also makes perfect sense. If there are two angles at the same location, then the corresponding recordings only get half of the weight.
-
Case (3) might actually be a bug. The coverage of the weights is larger than 180° and this case is probably not treated well.
For your -60°/+60° case, you should probably disable weighting the angles (if they are evenly distributed). Otherwise, I would be open to introducing another keyword argument that defines the desired spread of the angles...
Cheers!
