+specified, it sets the "accept" boolean to true.  Then for the current
+iteration as a whole we can run:
+
+	dettool -addetrunsummary -det_id <det_id> -iter <iter> -exp_id <exp_id> -bg <stat> -bg_stdev <stat> -bg_mean_stdev <stat> [-master]
+
+Which allows per detrend run iteration summary statics to be registered and
+can flag the iteration's results as being acceptable for use as a master.
 
 Once this has been done, a decision is made whether to make another
 iteration:
 
-	dettool -updatedetrun -det_id <det_id> -iter <iter> -bg <stat> -bg_stdev <stat> -bg_mean_stdev <stat> [-rerun|-ok|-stop]
+	dettool -updatedetrun -det_id <det_id> -iter <iter> [-rerun|-ok|-stop]
 
 where "-rerun" causes a new iteration to be started, "-ok" causes the
