splot FEROS spectra

Hi all

I downloaded FEROS spectra from the ESO archive, but I have problem when I use splot to see the spectrum.

Giving the command
splot r.FEROS.2007-01-30T01:57:04.945.1051.fits[*,1]

I get a plot not calibrated in lambda but in "position", starting from
about -30 to 30

can you help me in recover the correct lambda calibration?

thanks

Gianni
