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

24Using the tool
25--------------
26
271) Select *Slit Size Calculator* from the *Tool* menu on the SasView toolbar.
28
292) 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
343) 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
38the Q data. This calculator assumes the data has units of 1/\ |Ang|\ . If the
39data is not in these units it must be manually converted beforehand.*
