Subtract the dark current from a HFIR SANS data set. This algorithm is rarely called directly. It is called by HFIRSANSReduction.
This workflow algorithm will:
The dark current is subtracted pixel by pixel by normalizing the dark current data by counting time, as follows:
\(I'(x,y)=I_{data}(x,y)-\frac{T_{data}}{T_{dc}} I_{dc}(x,y)\)
where the T-values are the counting times for the data set and the dark current (dc).
