How have you set the measurements to be displayed?  For instance, have  
you run something like this...

IJ.run("Set Measurements...", "area standard centroid center perimeter  
bounding shape feret's display redirect=None decimal=3");

I suppose that you could work with the Analyzer class directly as an  
alternative.  That would be new territory for me, but perhaps  
something like...

Analyzer.setMeasurements(Measurements.AREA + Measurements.STD_DEV);

I haven't tested the above, but it might be worth giving it a whirl.
