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

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