The construction of CBF/imgCIF files can be simplified using templates. A template is itself an imgCIF file populated with data entries but without any binary sections. This file is normally associated with a CBF handle using the cbf_read_template call and provides a framework into which images and other experiment-specific data may be entered.
Fig. 5.6.4.1 is a sample template for an ADSC Quantum 4 detector (ADSC, 1997) with a κ-geometry diffractometer at Stanford Synchrotron Radiation Laboratory (SSRL) beamline 1–5.
The template for a MAR345 image plate detector (MAR Research, 1997) is almost identical. The major differences are in the size of the array (2300 × 2300 versus 2304 × 2304), the parameters for the CCD elements and the geometry of the elements. Therefore a few of the values in the AXIS, ARRAY_STRUCTURE_LIST, ARRAY_STRUCTURE_LIST_AXIS and ARRAY_INTENSITIES categories are different, as listed in Fig. 5.6.4.2.
