Hi Amy,

My reduction process is VLBATECR, VLBAEOPS, VLBACCOR, VLBAPANG, VLBAMPCL, VLBABPSS, VLBAAMP, apply geodetic data with CLCOR, global fringe fit with FRING, smooth with SNSMO, then CLCAL for each phase reference pair individually.  I only see the problem after running the final CLCAL.  

I've attached my delzn output, but even if I skip this step I still get the amplitude error after phase referencing with CLCAL. 

My inputs for CLCAL are, for example: source '0216+011'; calsour '0215+015'; interpol 'simp'; refant 9
