1) SNPLT (OPCO=IFDF) now plots no difference in rates (in Hz) between the IFs if the SN-table entries (in sec/sec) are independent of IF. 

This statement cannot be right - the SN rates you have shown me are dependent on IF and my fix should have made the displayed rates in SNPLT in mHz not depend on IF.  I think you meant dependent not independent in the last phrase.

FRING has always fit for parameters as it is now fitting.  Believe me - I have changed how data are fed to the fitter but I have neither the knowledge nor the inclination to change the fitter.  Thus if it fits in Hz now it has always fit in Hz (since Bill left AIPS anyway in about 1994).

I have yet to look at SNSMO and what you report is most curious.

I think I will need a TASAV file with the initial SN table from FRING in order to test things.  I have o data with real rates.
