- class txpipe.covariance.TXFourierGaussianCovariance(*args: Any, **kwargs: Any)[source]
Compute a Gaussian Fourier-space covariance with TJPCov using f_sky only
It imports TJPCov to do so, and runs at a fiducial cosmology.
This version does not account for mask geometry, only the total sky area measured.
- class txpipe.covariance.TXRealGaussianCovariance(*args: Any, **kwargs: Any)[source]
Compute a Gaussian real-space covariance with TJPCov using f_sky only
This version does not account for mask geometry, only the total sky area measured.
It is implemented as a subclass of the Fourier-space version, so also uses TJPCov and a fiducial cosmology.
- class txpipe.covariance.TXFourierTJPCovariance(*args: Any, **kwargs: Any)[source]
Compute a Gaussian Fourier-space covariance with TJPCov using mask geometry
This also calls out to TJPCov, using more recent additions to that package.
This version, for speed, re-uses the workspace objects cached in the twopoint fourier measurement stage.
