Websky 0.4 CMB Alms with higher ell_max #135

Open zonca opened 1 year ago

zonca commented 1 year ago

@xzackli, I would like to run Unlensed CMB with no solar dipole, however that combination is absent, can you please provide it?

@giuspugl @xzackli I noticed that the alms in websky 0.4 have a ell_max of 8250. Would it be possible to generate them with ell_max of 16384? That is the same ell_max of the new PySM3-native components.

in the meantime I need the unlensed maps without solar dipole because they are used by one of the predefined components, so I generated them myself, see notebook: https://gist.github.com/dde34e806c1949e38f8894ea6c3121ea

Still for later release of PySM I would like to have alms with higher ellmax

actually here is the notebook I used, just for later reference: https://gist.github.com/5f0a01c64b9e6b9a669836ac6f39ed17

This is something intrinsic to the Websky outputs. In principle don't foresee any issue for it , but we 've to reach out @georgestein and @marcelo-alvarez as developers of Websky . Will reach'em out and get back to you asap .
