New Revision: 18565

URL: http://svn.gna.org/viewcvs/relax?rev=18565&view=rev
Log:
Improved the default RDC and PCS errors for the frame order target functions 
if these are not loaded.

These now default to 1 Hz and 0.1 ppm respectively.  The previous 0.03 ppm 
PCS error default was far
too small, causing the PCS to have much more weight than the RDC.
