applying the ism for stars proved to be usefull

should we apply a local dust extinction for galaxies to ? then it has to be applied in obsframe

The extinction map from Planck is here :
http://pla.esac.esa.int/pla/aio/product-action?MAP.MAP_ID=HFI_CompMap_ThermalDustModel_2048_R1.20.fits
E(B-V) is in column 3
Coordonnées are available from HEALPIX reference system
https://sourceforge.net/projects/healpix/
There are routines that make the link between coordinates and pixel/row number.
This should be implemented in AMAZED and (at least) the Euclid pipeline. The correction on the continuum is the same as in the ISM fit but at redshift 0.
The correction should be optional, as simulated data might not be affected by MW extinction
