Hi Vincenzo

Any self-respecting program that computes anything from the delta-anoms
*should* (but it's always wise to verify that it does!) check that those
delta-anoms were actually measured (in an MTZ file this is flagged by
having sigma(delta-anom) > 0), and doesn't simply treat them as measured
with a value of zero.  In the case of centrics of course there is no
delta-anom to be measured (Friedel equivalents will be averaged), so no
E's should be generated from them.
