The datacard can also contain `$MASS` keyword, it allows to setup a single datacard for various mass points. It will be replaced with the value passed to `-m` option when running the tool. In addition, user-defined keywords can be used. Any word in the datacard `$WORD` will be replaced by `VALUE` when including the option `--keyword-value WORD=VALUE`. This option can be repeated multiple times for multiple keywords.

It is quite common to use data-drive background estimation methods. In Combine one can perform simultaneous fit of signal and control regions it allows to automatically handle the statistical uncertainty due to the number of data events in the control region, correctly handles signal contamination in the control region, allows to properly take into account systematic uncertainties affecting the backgrounds in the control regions.
