We compare the background subtraction based on the use of priors and on differential methods exploiting signal time dependence. We illustrate the impact of systematics such as the straylight. Finally, we address the problem of differences in the ZLE geometrical properties possibly relevant at these frequencies.STAMPAenConference paper10.1142/9789814623995_01972-s2.0-85045296797https://www.worldscientific.com/doi/abs/10.1142/9789814623995_01972015mgm..conf.1444MFIS/05 - ASTRONOMIA E ASTROFISICAERC sectors::Physical Sciences and Engineering::PE9 Universe sciences: astro-physics/chemistry/biology; solar systems; stellar, galactic and extragalactic astronomy, planetary systems, cosmology, space science, instrumentation
