This is 50 50 often difficult to do well and thus many data sets will include a background. 51 For those cases, the user should check the "estimate background" box and the 52 module will do its best to estimate it. 51 For those cases, the user should check the "Estimate background level" option 52 and the module will do its best to estimate it.
