MULTIPLY

        LAS\MULTIPLY Fact

    Multiply the R Observation by Fact. MULTIPLY leaves  the  T  Observation
    unaffected.  Note  that  Tsys  is also multiplied by the same (absolute)
    factor to keep proper weights. If only the data is to be multiplied, use
    the SIC\LET command on array RY:
        SIC\LET RY Fact*RY
