Removal of foreground emissions

• The Solar System - ZL:

  • Interplanetary Dust Particles
    • Reflected sunlight (1.25 - 3.5 mm)
    • Thermal dust emission @ T=260 K

• The Galaxy

  • Stellar sources (discrete and unresolved)
  • Star forming regions, molecular clouds
  • Thermal dust emission from the ISM

• Extragalactic sources: LMC and SMC
