Overview

Sheet 1: vims_wavcal

Please note that these wavelengths are applicable as of January, 2004. See the table below for corrections as a function of time. Please also note that channels 1-96 apply to the Vis channel only, and the corrections below only apply to the IR channel (channels 97-352 below). The shifts indicated apply for all channels within the IR array. The shifts were derived from an analysis of the position of Titan's infrared atmospheric windows and should be accurate to +- 1 nm. Further updates are forthcoming and will be derived using the VIMS internal calibration diode. At this point in time (November, 2014), there are no known differences between the initial wavelength calibration of the VIMS Vis array and that of the present.
