Gaussian integration over a grid
of 16 x 8 x 16 points = 2048 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) 0.301 0.394
range of gasket transmission (min-max) 0.973 1.000
range of P media transmission (min-max) 1.000 1.000

thickness of diamond anvil 1: 1.500 mm, mu = 0.2000 mm-1
thickness of platten 1: 3.300 mm, mu = 0.0500 mm-1

thickness of diamond anvil 2: 1.500 mm, mu = 0.2000 mm-1
thickness of platten 2: 3.300 mm, mu = 0.0500 mm-1

Gasket shadowing corrections were made based upon
Gasket thickness = 145.0 microns, radius = 250.0 microns
Gasket absorption coeff = 30.00 mm-1
REFLECTION WAS CONSIDERED TOTALLY OBSCURED IF
FRACTION CRYSTAL ILLUMINATED WAS LESS THAN 0.20
