## Public Member Functions

DataOptions ()
Default constructor: use the default options. More...

## Public Attributes

bool fAsymErrors
use asymmetric errors in the value when available, selecting them according to the on sign of residual (default is true) More...

bool fBinVolume
normalize data by the bin volume (it is used in the Poisson likelihood fits) More...

bool fCoordErrors
use errors on the x coordinates when available (default is true) More...

bool fErrors1
use all errors equal to 1, i.e. fit without errors (default is false) More...

bool fExpErrors
use expected errors from the function and not from the data More...

bool fIntegral
use integral of bin content instead of bin center (default is false) More...

bool fNormBinVolume
normalize data by a normalized the bin volume (bin volume divided by a reference value) More...

bool fUseEmpty
use empty bins (default is false) with a fixed error of 1 More...

bool fUseRange
use the function range when creating the fit data (default is false) More...
