This algorithm extends the TOFSANSResolution to implement the experimentally determined TOF resolution for EQSANS.
The Q resolution for a TOF SANS has two components: a geometrical contribution and a contributions from the resolution in TOF.
The TOF resolution for EQSANS was measured to be:
where is the wavelength and
This algorithm is generally not called directly. It’s called by EQSANSAzimuthalAverage1D after the calculation of I(Q). It can only be applied to an I(Q) workspace.
