DESCRIPTION           = "The Planetary Fourier Spectrometer (PFS) experiment
 on board the Mars Express mission has two channels covering the 1.2-5 
 microns ( SWC)  and the 5-50 microns ( LWC ) . The Long Wawelength Channel 
 (LWC)  measures the thermal emission spectrum of Mars between 200cm-1 and 
 2000cm-1  with a spectral resolution of 1.4 cm-1, in absence of 
 apodization. We present  here the calibration of this channel and its 
 performance . The instrument  calibration has been performed on ground , 
 before launch , in space during Near  Earth Verification (NEV) 
 measurements, and at Mars . Special attention has  been given to the 
 problem of microvibrations on board the spacecraft.  In order to obtain 
 correct results , the source-instrument-detector interaction is  studied 
 very accurately. The instrument variations during a pericentre pass  impose 
 a complex procedure for the LW channel calibration, but fortunately the 
 procedure adopted seems to work well. Samples of the calibrated data are 
 given  (as single spectrum and as an average over a few spectra) to show 
 the  performance of the experiment and its scientific 
potentialities."
