Add ISIS SANS 'what is calculated' documentation

[Anders Markvardsen]

http://www.mantidproject.org/ISIS_SANS contains various documentation about, how to use gui, batch files, user file commends, scripting....

But is missing documentation that gives a description of what is actually calculated in the SANS reduction, without saying in much detail how (since this may change).

Add 'what is calculated' documentation.

The audience/purposes are:

• To help other facilities to understand what sans reduction calculates

• To help developers understand what is calculated

• To help new instrument scientists and isis users

Put as critical, since there is a certain urgency for Bilby to use/modify Mantid SANS

http://www.mantidproject.org/SANS_ISIS_Data_Reduction has been created. Thanks to Richard for feedback to this page.

This page now links from http://www.mantidproject.org/ISIS_SANS and added as an example of using q1d in q1d rst documentation

[Anders Markvardsen]

To test:

1. check that http://www.mantidproject.org/SANS_ISIS_Data_Reduction exist and is linked from http://www.mantidproject.org/ISIS_SANS

2. check that it is linked from Q1D rst documentation also

remember to merge branch into master.

Optionally, please do not hesitate to provide any comments to the content of http://www.mantidproject.org/SANS_ISIS_Data_Reduction

The new SANS_ISIS_Data_Reduction' page is linked from the main ISIS SANS page, and also from thew new Q1D-v2 algorithm documentation (rst). Some clarifications have been also made in the algorithm source code. All code modifications look fine.

I read the new page from the viewpoint of an ignorant developer that wants to understand what it does. I think it is overall good and accessible. These are my comments and suggestions:

• I get an idea of what each term is and how it is obtained
• I get a good idea of how the ISIS implementation works and the steps involved.
• It definitely helps to understand what the commands in the ISIS-SANS example scripts do, and what the ISIS-SANS GUI tabs and components are about.

I couldn't come up with any relevant improvement or suggestion, I think all the pieces fit well together. I just took the liberty to edit a few typos and details in this and other SANS wiki pages.
