nenupy.astro.astro_tools.sky_temperature

nenupy.astro.astro_tools.sky_temperature(frequency=<Quantity 50. MHz>)[source]

Sky temperature at a given frequency frequency (strongly dominated by Galactic emission).

\[T_{\rm sky} = T_0 \lambda^{2.55}\]

with \(T_0 = 60 \pm 20\,\rm{K}\) for Galactic latitudes between 10 and 90 degrees and \(\lambda\) the wavelength.

Parameters:

frequency (Quantity) – Frequency at which computing the sky temperature. Default is 50 MHz.

Returns:

Sky temperature in Kelvins

Return type:

Quantity

Example:

from nenupy.astro import sky_temperature
import astropy.units as u

temp = sky_temperature(frequency=50*u.MHz)
