This script corrects for gain artefatcs of the CCD by moving the spectrum to different places on the 2k x 2k CCD camera. In the presence of a sharp peak (e.g. the zero-loss peak) it can also align the spectra before summing them up, or record a time series … WebThe difference between EFTEM and these other TEM imaging techniques is that for EFTEM imaging, an "energy filter" is placed between the specimen and the plane where the final … perryopolis funeral home
