  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)      0.407     0.454
         range of gasket transmission (min-max)           0.997     1.000
         range of P media transmission (min-max)          1.000     1.000

       thickness of platten 2:  0.000 mm, mu =  0.0000 mm-1

    Gasket shadowing corrections were made based upon
    Gasket thickness = 150.0 microns, radius = 212.0 microns
    Gasket absorption coeff =        21.00 mm-1
    REFLECTION WAS CONSIDERED TOTALLY OBSCURED IF
