hera_sim.noise.resample_Tsky¶
- hera_sim.noise.resample_Tsky(lsts, freqs, Tsky_mdl=None, Tsky=180.0, mfreq=0.18, index=-2.5)¶
Evaluate an array of sky temperatures.
- Parameters:
lsts (array-like of float) – LSTs at which to sample the sky tmeperature.
freqs (array_like of float) – The frequencies at which to sample the temperature, in GHz.
Tsky_mdl (callable, optional) – Callable function of
(lsts, freqs)
. If not given, use a power-law defined by the next three parameters.Tsky (float, optional) – Sky temperature at
mfreq
. Only used ifTsky_mdl
not given.mfreq (float, optional) – Reference freq for sky temperature. Only used if
Tsky_mdl
not given.index (float, optional) – Spectral index of sky temperature model. Only used if
Tsky_mdl
not given.
- Returns:
ndarray – The sky temperature as a 2D array, first axis LSTs and second axis freqs.
