Linearizing STIS wavelength scales
Guest wrote on Dec 19, 2006
Hi,
I am using spectroscopic data from STIS on HST which is in echelle format and has a non-inear wavelength scale. I want to convert this non-linear wavelength scale to linear scale. I tried to find an IRAF task which can do this but have been unsuccessful. Please let me know if there is a task in IRAF which will do this.
Thank you so much,

DISPCOR in the ONEDSPEC package should be able to do this, post back if you're still having problems.
