A calibration technique has been developed utilizing normalized intensities measured at seven different He I filter positions which are used to infer the line-of-sight velocity of structures observed with the MLSO CHIP He I filter. To obtain He I intensity, the output from each of the seven filter positions are normalized to reflect only the photosheric continuum radiation and the He I 1083 nm absorption or emission line. Velocity is inferred from an application of these normalized intensities to an algorithm derived from an empirical analysis of synthetic spectra. Both the normalization technique and the application of the algorithm are presented as well as some example events.
