Lachlan's scheduling is ideal : summer in UK and summer
in AU, so as to have burned skin the whole year (though
is there sun in UK in summer ?-).
Here are new warm data recorded at 23C on a brand new
D8 Bruker diffractometer (no royalties for me) concerning 2
well known standards :
NAC (Na2Ca3Al2F14 used for calibrating INEL detectors)
NIST 1976 (Al2O3)
Refinements with (for NAC) and without structure are presented.
Data may be downloaded at :

Minimum FWHMs are near of 0.045-0.051 (2-theta degrees).
