Please see Chapter 4 in the Reference Manual, which describes the
various types of gb supported with Amber. Table 4.1 shows the radii
that are recommended for each variant.
I'm not sure I'm answering your question, though. You might want to
look at papers that carry out similar calculations, or consult a recent
review:
