Upgrading foreground templates to ~arcmin resolution #23

I am interested in using the python sky model to simulate galactic foregrounds at high spatial resolution (~1 arcmin) for the preparation of upcoming sub-mm surveys. This would require to upgrade the maps to a healpix nside of 4096 or even 8192. The PySM paper shows that small scale features can be added to the map by extrapolation of the power spectrum to high ell and by modifying the synfast proposal distribution for generating random a_lm. However, it seems like this part of the code is not public at the moment. Would it be feasible for you to share the code for adding small scale features to the maps?
