Currently the field regions are generated in a spiral around the cluster region. The limit is the size of the field around the cluster region, which determines how many field regions can be defined.
A different approach would be to define random field regions as done in Angelo et al. 2016.
A way to do this with ASteCA would be to randomly select field bins until de area of the cluster is matched. This would allow to define a lot more field regions, since a single bin can be reused many times.
Not sure about the statistical implications of this method though.
