1. Use Lorentzian profile for smoothing (but not yet for message averaging).
2. Add ability to set ndepth and do message averaging ti fer65. 3. Correct SNR values for measured Doppler width. 4. Comment out the "write(62..." diagnostics. git-svn-id: svn+ssh://svn.code.sf.net/p/wsjt/wsjt/branches/wsjtx@6537 ab8295b8-cf94-4d9e-aec4-7959e3be5d79
