Name:'DIFFRN_STANDARD_REFLN'
Parent category:
DIFFRN_STANDARDS
Definition:
Data items in the DIFFRN_STANDARD_REFLN category
record details of the `standard' reflections
measured repeatedly to monitor variations in intensity due to source
flux, environment conditions or crystal quality.
Note that these are the individual standard reflections, not the
results of the analysis of the standard reflections.
Category is of type Loop
