[Rasch] Basic MFRM question

I've been using FACETS to analyse rater, student and station facets in
Raters are nested within station (mostly, except for emergency swaps)
and I have a subset warning.
I fixed the subset problem by using the FACETS subset group anchor file
for rater and rerunning the analysis with this output in the rater
labels in the control file. (on the assumption that raters vary randomly
from the mean, now group anchored to 0).
Problem is, I don't really understand what I have done! And how can I
check this new result for validity and fit to the Rasch model?
