Powder dictionary (pdCIF) version 1.0.1




   Length of the specimen that is illuminated by the radiation
   source (in millimetres) for instruments where
   the illumination length varies with 2\q (fixed
   divergence slits). The _pd_instr_var_illum_len
   values should be included in the same loop as the
   intensity measurements (_pd_meas_).

   See _pd_instr_cons_illum_len for instruments where
   the divergence slit is \q-compensated to yield a
   constant illumination length.
