New Ticket: UVPRT - incomplete/misleading output

UVPRT prints out two copies of the reference frequency, but does NOT seem to print out the actual frequency of the selected channel, even though it *does* print out the uvw values in wavelengths *for the selected channel* (rather than wavelengths at the ref. freq)

UVPRT' prints out values of u,v,w (in wavelengths) at the frequency of the selected channel.  It says, correctly:
"U, V, W are in Kilo wavelengths at the selected frequency"

It then says:
"Ref freq=  4.812249864 GHz  Ncor=  4  No. vis=     14475  Sort order= TB"

so far so good, user has been told what reference frequency is.

However,  then it has a line like this:
"Source= 0716+714    Freq=   4.812249864    Sort= TB        1   I"

I think most people would expect the "Freq" in this line to indicate the "selected frequency" ie that of the selected channel.  It seems to be, however, just the reference frequency again.  I think this second line should give the "selected frequency", perhaps saying "Selected Freq=" just to be unambiguous.
