ftsdata.get_ils_kernel

ftsdata.get_ils_kernel(opdmax_mm, dfreq_GHz, n_points=1001, onesided_apodization=None)[source]

Retrieve the ILS of a given FTS observation as an astropy.convolution.Kernel.

Parameters:
opdmax_mm: float

the maximum opd of the observation in mm

dfreq_GHz: float

the requested frequency scale in GHz

n_pointsint, optionnal

the number of points for the kernel (odd number), default 1001

onesided_apodization[function], optional

apodization function to be used on the one sided interferograms, by default None

Returns:
kernelastropy.convolution.CustomKernel

the kernel to be used for spectral convolution.
