symmetry information in preference to the above space-group names.

Data were collected at room temperature and pressure of 3.15(3) GPa
(3150000 kPa). 
Pressure was determined by monitoring the shift of the ruby
R1-fluorescence line.
"_diffrn_measured_fraction_theta_full" value is low, because 
the access to the reciprocal space is restricted due to the use of
the diamond anvil cell.

Gaussian integration over a grid
of 16 x 16 x 16 points =  4096 total grid points
  Based upon method of Burnham (1966)

 Data corrected for diamond-anvil cell absorption
 Note that exptl_absorpt_correction_tmin and _tmax
 the total correction factors applied to the intensities
 The individual factors are: 
         range of dac transmission factors (min-max)      0.694     0.726
         range of gasket transmission (min-max)           0.470     1.000
         range of P media transmission (min-max)          1.000     1.000

 thickness of diamond anvil 1:  8.000 mm, mu =  0.0200 mm-1
       thickness of platten 1:  0.000 mm, mu =  0.0000 mm-1

 thickness of diamond anvil 2:  8.000 mm, mu =  0.0200 mm-1
       thickness of platten 2:  0.000 mm, mu =  0.0000 mm-1

    Gasket shadowing corrections were made based upon
    Gasket thickness = 300.0 microns, radius = 161.0 microns
    Gasket absorption coeff =        30.30 mm-1
    REFLECTION WAS CONSIDERED TOTALLY OBSCURED IF 
 FRACTION CRYSTAL ILLUMINATED WAS LESS THAN 0.00
