MODIFY DOPPLER

        LAS\MODIFY DOPPLER [SIGN|*|Value]

    Change the Doppler factor according to the CLASS convention (-V/c). With
    no argument, checks whether the header  value  is  consistent  with  the
    CLASS value computed according to the date and observatory. The checking
    precision  corresponds  to  0.6  m/s  in  V.  A  logical  SIC  variable,
    DOPPLER_PB,  is  set  to  true if the values disagree. If an argument is
    present:

    SIGN    change the sign of the Doppler factor but do not recompute it,
    *       compute and update the Doppler factor,
    Value   set the Doppler factor to <Value>
