NEWVEL

    [NOEMAOFFLINE\]NEWVEL VType Value [Tolerance] [/FIXEDEQ] [/SETUP]

    Applies  the  current backend configuration to a source at different LSR
    velocity or redshift to compare the frequency coverage of  high  resolu-
    tion  spectral windows. With Vtype LSR (resp. REDSHIFT), Value should be
    the LSR velocity in km/s (resp. the redshift) for which  the  comparison
    is desired. The shift in REST frequency coverage between the two sources
    is computed and compared to a tolerance (in MHz) that can  be  given  as
    third argument (0 is the default value).

    With  the  option  /FIXEDEQ, the tuning for the new redshift or velocity
    will not be adapted to match the optimized tuning grid (as a result, the
    frequency coverage offset is null)
