DAC_Abs_Correction
Description: Absorption correction for diamond anvil cell data. Corrects intensity decrease with increasing 2-Theta due to longer beam paths through diamonds.
Comment: Actually not a macro, the structure of diamond in included with a scale factor of zero to calculate the correct value for u_per_cm_diamond for any given wavelength.
