Web26 Sep 2024 · By fitting the three molecular spectra of OH (A-X), NH (A-X) and N 2+ (B-X), the relationship between the rotation temperature of the local arc and the leakage current was obtained, and the results show that the local arc rotation temperature increases with the increase in the leakage current amplitude [21,22]. S. WebSince the temperature of the CMB is measured to be 2.73K, this makes the fluctuations 1 part in 100,000 as advertised. Mathematically, the power spectrum is actually equal to the square of this quantity times 2π/ [l(l+1)], where the l's are there to account for the fact that the sky is two dimensional.
