Provided is a catalyst system for polymerization of monomers having at least one Ziegler-Natta polymerizable bond, comprising:. The wafer is annealed in an apparatus including a cavity and a radiation source of a wavelength ranging from 10\u201325 \u03bcm and more particularly 15\u201318 \u03bcm, or a frequency ranging from 12\u201330 THz and more particularly 16. Methods of using the attenuated pathogens as immunogenic compositions are also disclosed. Correction parameters used to correct the first image data which depends on the first light condition into image data which depends on the second light condition are generated based on the first and second color signal values. The up-sampling part supplements delay profile data at sampling time that has been lost in the down-sampling part.
