XafsTransmissionMapping
XafsTransmissionMapping objects encapsulate the mapping for XAFS experiments which contain transmission data. The destination columns are: 'Energy' -- energy values for each data point 'Io' -- initial beam intensity 'It' -- transmission detector intensity The destination column 'Mu' is calculated from 'It' and 'Io' using the formula 'Mu = log(Io/It)'.
Method Summary | |
---|---|
Create a new XafsTransmissionMapping object, assigning source column names via keyword arguments. | |
make_Iref(self,
data,
result)
| |
Calculate Mu when the mapping object is applied to 'data'. | |
Inherited from Mapping | |
Apply this mapping to the xdp.Data object 'data'. | |
Virtual method which is called to finalize the xdp.Data object 'data' before it is returned. |
