I am looking for the exact definion of '_gsas_i100_meas' tag which appears 
usually
in a CIF output after GSAS runs. Could anybody know it?

Dear Artem,

If you look at this:
loop_
      _refln_index_h
      _refln_index_k
      _refln_index_l
      _refln_observed_status
      _refln_F_squared_meas
      _refln_F_squared_calc
      _refln_phase_calc
      _refln_d_spacing
      _gsas_i100_meas
   0   2   0 o  543.057   563.524    0.00    5.51152  19.55
   0   2   1 o  745.908   780.430   180.00   4.39756  37.37
   1   1   0 o  1633.500  1662.608  180.00   3.93794  63.39

....
then it is not so difficult to guess that it is the intensity of the reflection normalized to the strongest reflection in the set (which is given 100).

best wishes, Arie
