Dust spectral index and temperature based on GNILC #69
Comments
Hi @zonca. |
no @NicolettaK thanks, I think it would be better to use the GNILC products for templates / spectral indices / dust temperature |
I've finalized a procedure to inject smaller angular scales to the spectral parameters.

@giuspugl the notebook for spectral index and T dust is at https://github.com/galsci/pysm/blob/f3b79810d22805cf5b0904eb13f65df6c6b6dbed/docs/preprocess-templates/gnilc_dust_spectral_index_T_dust.ipynb Instead of recomputing the modulation factor in that notebook, can I load the modulation map for T that I have created in the notebook which creates the templates? Or do they differ somehow? |
I am referring to the modulation alms saved in cell 44 of https://nbviewer.org/gist/zonca/b0ec6cc14fa4c22ded497cc445a7ea46#Define-Modulation-maps |
Sorry about that ! Here you can find an updated notebook
Yes! the modulation for Td and Beta_dust is the same as the intensity one. |
What do you think about the reusing the same modulation map?

i made sure it is compiled also for the spectral parameters too .

Reusing the modulation map seems fine to me as long as the fluctuations themselves are different. Physically it is sensible for the amplitude of fluctuations to be related to the total intensity. |
Implemented in #104 |
See comparison between GNILC and PySM 2 here:

Suggestion by Hans Kristian (referring to the PySM 2 templates) was:
However no idea how to proceed. @brandonshensley @NicolettaK?
