A Python package to compute Minkowski Functionals of input fields, as well as their expected values in the case of Gaussian isotropic fields.
The formats supported for input data are the following:
- Scalar HEALPix maps, as the ones used by healpy (see paper).
...and more to come, feel free to contact us (by email or opening an issue) to implement more schemes.
The theoretical expectation for Gaussian isotropic fields are implemented in the following cases:
- Gaussian scalar maps on the sphere (such as CMB
$T$ , see paper). -
$\chi^2$ maps on the sphere (such as CMB$P^2$ , see paper).
...and more to come, feel free to contact us (by email or opening an issue) to implement more theoretical expectations.
