For plots LSS_WAVE2 (arc line fluxes from the IRDIS LSS grism setup) and IRDIS_LSS_WAVE4
(arc line fluxes for the IRDIS LSS prism setup), the FULL version of box 3 shows
the long-term behavior of the L3=1.545 mu lamp. In addition the scaled
long-term behaviour of flux of the same lamp as registered in the much
more frequently acquired IFS WAVE calibrations is shown, to visualize deviations of the 
LSS L3=1.545mu flux from the known long-term behavior.
