TEMP T [20]Sets the temperature T of the data collection in degrees Celsius. This is reported to the .cif file and used to set the default isotropic U values for all atoms. TEMP must come before all atoms in the .ins file. TEMP also sets the default X-H bond lengths (see AFIX) which depend slightly on the temperature because of librational effects. The default C-H bond lengths and default U-values are rounded to two decimal places so that they may be quoted more easily.
