error_control

• type: setup command
• function: overall control of random errors.

&error_control
    long clear_error_settings = 1;
    long summarize_error_settings = 0;
    long no_errors_for_first_step = 0;
    STRING error_log = NULL;
    double error_factor = 1;
&end

• clear_error_settings -- Clear all previous error settings.
• summarize_error_settings -- Summarize current error settings. If non-zero, then the command has no other function except showing a summary of the current error settings.
• no_errors_for_first_step -- If non-zero, then there will be no errors for the first step. This can be useful for fiducialization of phase and momentum profiles.
• error_log -- The (incomplete) name of a SDDS file to which error values will be written. Recommended value: ``%s.erl''.
• error_factor -- A value by which to multiply the error amplitudes in all error commands.

The proper use of this command can be confusing. A typical sequence will be as follows:

&error_control
 clear_error_settings = 1,
 error_log = %s.erl
&end

&error_element ... &end
&error_element ... &end
.
.
.
&error_element ... &end

&error_control
 summarize_error_settings = 1
&end
