[daip] AIPS query

Hi there

I hope this is just a quick question and would really appreciate any 
suggestions you have.

Is it possible to plot polarisation vectors, the length of which indicate 
the fractional polarisation instead of the linear polarisation? I've used 
COMB to create both LP and FP images but am finding PCNTR will only use 
the LP image for the vector lengths. If I try using the FP image the 
output is:

msslth> PCNTR1: Task PCNTR  (release of 31DEC04) begins
msslth> PCNTR1: Do grey scale:
msslth> PCNTR1: End labeling:
msslth> PCNTR1: Start contouring
msslth> PCNTR1: Start polarization lines
msslth> PCNTR1: POLDRW: PLOT ROUTINE ERROR  3 QUITTING
msslth> PCNTR1: GFINIS: number records used      74
msslth> PCNTR1: Successful plot file version    8  created.
msslth> PCNTR1: Appears to have ended successfully

Many thanks
