IXTmoments contains various information about the moments of a peak. For instance the mean and skewness.
Structure
The elements of the object are as follows:
| Field | Type | Description |
|---|---|---|
| base | IXTbase | used internally |
| area | IXTdatum_array | area of each peak and its error |
| bkgd_xmean(:) | real(ptr) | background level of each peak at the value of the first moment of x |
| bkgd_error(:) | real(ptr) | slope of background of each peak at that position |
| xmax(:) | real(ptr) | position of of each peak maximum |
| c_fwhh(:) | real(ptr) | half-way position between the peak half-heights |
| fwhh(:) | real(ptr) | full width half height |
| xmean | IXTdatum_array | first moment of each peak |
| sigma | IXTdatum_array | second moment of each peak |
| g1 | IXTdatum_array | skewness of each peak |
| g2 | IXTdatum_array | kurtosis of each peak |
