_diffrn_refln.counts_bg_1
Name:_diffrn_refln.counts_bg_1
Alias:
_diffrn_refln_counts_bg_1
Definition:
The measured background scattering on one side of a diffraction
peak when measuring using a point detector.
Note that counts-per-second values should be converted to
total counts.
Standard uncertainties should not be quoted for these values.
If the standard uncertainties differ from the square root of
the number of counts, _diffrn_refln.intensity_* should be used.
Type: Integer
Units: counts
The permitted range is 0 → infinity
Category:
