| 2 | ============= |
|---|
| 3 | |
|---|
| 4 | SANS Models version 0.4.1 |
|---|
| 5 | |
|---|
| 6 | Package name: sans.models |
|---|
| 7 | |
|---|
| 8 | 1- What's New in Version 0.4.1 |
|---|
| 9 | - Release date: 6/9/2008 |
|---|
| 10 | - Modified non-shape models so that the 2D output is the 1D output for the length of Q |
|---|
| 11 | |
|---|
| 12 | Version 0.4.0 |
|---|
| 13 | - Release date: 4/15/2008 |
|---|
| 14 | - Added shape-independent models. |
|---|
| 15 | |
|---|
| 16 | Version 0.3.2: |
|---|
| 17 | - Release date: 2/14/2008 |
|---|
| 18 | - Added models to be used in magnetic analysis. |

| 21 | 2- Downloading and Installing |
|---|
| 22 | |
|---|
| 23 | 2.1- System Requirements: |
|---|
| 24 | - Python version >= 2.4 should be running on the system |
|---|
| 25 | |
|---|
| 26 | 2.2- Installing: |
|---|
| 27 | - Get the code from svn://danse.us/sans/releases/sansmodels-0.4.0 |
|---|
| 28 | - Execute the following: |
|---|
| 29 | python setup.py install |
|---|
| 30 | |
|---|
| 31 | 3- Known Issues |
|---|
| 32 | |
|---|
| 33 | 3.1- All systems: |
|---|
| 34 | - Q range validity of I(q) calculations. |
|---|
| 35 | Our 1D models of I(q) use the function of the NCNR library |
|---|
| 36 | for their IGOR package (Klein, 2006). That library uses a |
|---|
| 37 | fsat integration technique in some of its models (cylinders |
|---|
| 38 | and ellipsoids). Integration is done using 76 points in the |
|---|
| 39 | angle between the axis of the object and the q-vector, which |
|---|
| 40 | translates in a larger inaccuracy at high q. Integratiing |
|---|
| 41 | the 2D model I(q,phi) over all orientations of the object |
|---|
| 42 | will not yield the exact same result as the NCNR calculation |
|---|
| 43 | for q > 0.3 A-1. |
|---|
