Search range definition in local refinement?

Hi,

When I use local refinement, often it seems that the per-iteration changes in angles & shifts are larger than specified in the search range. Why is this?

Hi @olibclarke!

The plot limits and search extent parameters differ for two reasons:

  1. The main reason is that these limits are set per dimension. So for example, for translation you’ve limited the search to 2 Å in both X and Y, meaning the greatest distance a particle can move is ~2.8 Å.
  2. The second reason is that we plot the shift in pixels, but the parameter is in Å. We agree this is confusing, so I’ve noted that we should make the plot also in Å.

Ah! That is very helpful, thanks @rposert!
