  lan_rate_stream::compute_errors
        Calculate the error bars, given the rates and acucmulations

  Call:
        strref -> compute_errors

  History:
        Original: 3/1/92; SJT
        Allow for possibility of negative rates arising from
                background subtraction; 27/7/93; SJT
        Cope properly with low cadence data: 17/11/93; SJT
        Add trk errors: 18/11/93; SJT
        Make use raw_rates to give right values after bg subtraction:
                                23/11/93; SJT
        Add support for plotting against sc position: 22/2/94; SJT
        Include singles duty cycles: 29/4/94; SJT
        No ephem plotting in ULA data: 21/9/94; SJT
        Add options for |lat|: 1/5/95; SJT
        Converted to stream method: ?????; SJT
        Fixed doc comments: 5/2/02; SJT
        Made to actually work for unaveraged, no-unit cadence data:
        6/2/02; SJT
        Really made to work: 15/7/02; SJT
