Data were collected at room temperature and pressure of 4.46(3) GPa
(4460000 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.

  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)           0.328     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 = 180.0 microns
    Gasket absorption coeff =        30.30 mm-1
    REFLECTION WAS CONSIDERED TOTALLY OBSCURED IF 
 FRACTION CRYSTAL ILLUMINATED WAS LESS THAN 0.00
