_pd_instr_var_illum_len

Name:
'_pd_instr_var_illum_len'

Definition:

   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.
