vac2air -- Convert wavelength scales from vacuum to air above 2000 angstroms.
vacwair input output
vac2air converts wavelength scales from vacuum to air above 2000 angstroms. vac2air processes all groups of a multigroup GEIS file. Please note that vac2air works ONLY for GEIS image files, such as the C0H files produced for GHRS and FOS data.
- input [image file name]
