EQ-SANS: write TOF structure algorithm

Reported by: Mathieu Doucet Owned by: Mathieu Doucet

Blocking: Tester: Janik Zikovsky

Description

The recorded TOF values for EQ-SANS have to be modified by an offset before use. In addition, there is a "phase shift" such that two TOF regions are populated within one data acquisition frame. Those two regions need to be swapped and stitched together. The procedure is different depending on whether the so-called frame skipping is used.

(In [8240]) First cut at EQSANS TOF structure algo. Needs test, doc and frame skipping. Re #2078

comment:3 Changed 10 years ago by Mathieu Doucet

(In [8767]) Added system test. Since this algo can only be verified by running it on data, we will not create a unit test for it. Re #2078

Tried it with sample data in test directory and it looked reasonable.
