Um, can't resist here (although not directly relevant to the original
question):
1) Your dataset has a high overall Rmerge. The outmost shell (70%) is
very high, which suggests a need to shrink resolution. What about
I/s(I), redundancy and completeness? Also, how many
reflections (percentage) have been subjected to rejection? Too many
rejections may mean a SG error.
Outer shell Rmerge will always be very high: it's a mathematical thing,
R-distributions of small values are always crap, which is exactly what
Is at the highest res are: small values.
Only I/sigI (and completeness, although it's related) is really relevant
for deciding high resolution cutoff.
