Calibrations contain information regarding energy, full width at half maximum (FWHM) and efficiency calibrations. They must be selected and loaded for analyses (see Analysis Parameters). In LVis GammaVision calibrations (.CLB files) or any calibrated LVis measurement file (.LVM files) can be used as a source of calibration.

In each LVis measurement, the calibration is presented in its own tab (see as well Changing a Calibration in an .LVM file).
