renorm

Renormalize model, or change renorm conditions.

XSPEC> renorm [AUTO | NONE | PREFIT]

The renorm command will adjust the normalizations of the model by a single multiplication factor, which is chosen to minimize the fit statistic. Such a renorm will be performed explicitly whenever the command is used without a key-word, or during certain XSPEC commands, as determined by the following key-words:

• AUTO - Renormalize after a m odel, n ewpar, and before a f it.
• PREFIT - Renormalize only before a f it.
• NONE - Perform no automatic renormalizations, i.e., only perform them when a renorm command is given explicitly.
