_diffrn_refln.counts_peak

Name:
_diffrn_refln.counts_peak

Alias:
_diffrn_refln_counts_peak

Definition:

   
    Counts measured in the reflection peak before background
    subtraction. That is, the region of interest consists of
    only the diffraction peak.

    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:
diffrn_refln
