ITU-R P.372-9 gives the common methodology for specification of noise electromagnetic pattern in four environmental categories plus galactic noise. While predicting the expected noise levels, the characteristic trends with frequency, time of day, season, and the geographical location are taken into account explicitly.
Operating at exactly 3 millimeters - the wavelength at which total galactic noise is at a minimum -- Python may soon rival ACME-HEMT as the most sensitive medium-angle experiment so far conducted, says co-investigator Mark Dragovan of Princeton University.
It includes galactic noise, atmospheric noise and man-made noise.
