Smoothing setting in extracting inversion results of source reconstruction in SPM

In the batch GUI or the code for outputting inversion results, there is a parameter for "the number of iterations for smoothing ". Does this parameter correspond to the FWHM in mm?

For example, if I set it to 8 (matlabbatch{1}.spm.meeg.source.results.smoothing = 8;) , does it mean the FWHM for smoothing is 8 mm?

Version:

SPM 12

Environment:

Matlab on Win10

Thank you!
