+(1) Extracted from {{::salt2-4_data.tgz|}} (md5:af829c7f177c6037adcbe0a89360464a) that can also be found in the [[http://supernovae.in2p3.fr/sdss_snls_jla/ReadMe.html|SDSS-II/SNLS3 Joint Light-curve Analysis data release page]].
+(2) Data set should be used with code version 2.2.0 or higher. The same applies to more recent versions.
+===== Description =====
+The archive file contains all the data that define the model.
+**SALT2**
+  * ''salt2_template_0.dat''	Average spectral sequence
