=============
Template Data
=============

The simulation of the following foreground components requires specific
template map(s) and/or observational/simulation catalog(s) as the input:

* ``galactic/synchrotron``:
  requires the Haslam 408 MHz survey as the template map, and the
  spectral index map.
* ``galactic/freefree``:
  requires the Hα map and the dust map.
* ``galactic/snr``:
  requires the catalog of the Galactic SNRs.

The following template data are provided:

* Haslam 408 MHz all-sky survey:

The above all-sky maps are in HEALPix format.
Sky patches can be cut out from them using the ``get-healpix-patch`` tool.
The ``fg21sim-download-data`` tool can also be used to retrieve the above
template data by providing with the `data manifest <../data/manifest.json>`_.
