+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:
+
+* Galactic SNR catalog:
+  `GalacticSNRs_Green2014.csv <https://onedrive.live.com/download?cid=6BC61834227AC6CE&resid=6BC61834227AC6CE%2116026&authkey=AJcYjHaI7O7FEcY>`_,

+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>`_.
