I am in the process of changing RLDLY to correct phase as well as
delay.  That should fix things for your case.  It does not for the eVLA 
case where IFs 1-8 get 1 RLDLY solution and IFs 9-16 get another but the 
IFs have all had separate CALIB solutions and so are not phase aligned.

PCAL is a polarization solution task and has nothing to do with pulse 
cal tones.  RLDIF is only meaningful if there are polarization D term 
solutions.
