SET FREQUENCY

        CLIC\SET FREQUENCY subband sideband name freq
        CLIC\SET FREQUENCY ALL name freq

    Select  the  line  name  and frequency to be used to define the velocity
    scale, for the given sub-band and sideband, by the commands MODIFY  FRE-
    QUENCY and MODIFY DOPPLER.

    subbands;  'sideband'  must  be either USB or LSB; 'name' is a (max.  12
    character) mnemonic for the line name; 'freq' is the rest  frequency  in
    MHz.   If the line name is '*', then the default frequency entered prior
    to the observation will be used to compute the velocity  scale  for  the
    corresponding subband.

    "SET  FREQUENCY   ALL"   will  fill  in  the  given  frequency  for  all
    subbands.
