| 10 | Description |
|---|
| 11 | ----------- |
|---|
| 12 | |
|---|
| 13 | This tool enables X-ray users to calculate the slit size (FWHM/2) for smearing |
|---|
| 14 | based on their half beam profile data. |
|---|
| 15 | |
|---|
| 16 | *NOTE! Whilst it may have some more generic applicability, the calculator has |
|---|
| 17 | only been tested with beam profile data from Anton-Paar SAXSess*\ |TM|\ |
|---|
| 18 | *software.* |

|---|
| 21 | |
|---|
| 22 | Using the tool |
|---|
| 23 | -------------- |
|---|
| 24 | |
|---|
| 25 | 1) Select *Slit Size Calculator* from the *Tool* menu on the SasView toolbar. |
|---|
| 26 | |
|---|
| 27 | 2) Load a beam profile file in the *Data* field using the *Browse* button. |
|---|
| 28 | |
|---|
| 29 | *NOTE! To see an example of the beam profile file format, visit the file |
|---|
| 30 | beam profile.DAT in your {installation_directory}/SasView/test folder.* |
|---|
| 31 | |
|---|
| 32 | 3) Once a data is loaded, the slit size is automatically computed and displayed |
|---|
| 33 | in the tool window. |
|---|
| 34 | |
|---|
| 35 | *NOTE! The beam profile file does not carry any information about the units of |
|---|
| 36 | the Q data. This calculator assumes the data has units of 1/\ |Ang|\ . If the |
|---|
| 37 | data is not in these units it must be manually converted beforehand.* |
