    keyword=scaler server mods.

    I made a couple changes to the scaler server.

    1. Turned on "ignore_err" flag, so the warnings/errors don't
    bother people ("helicity error, you are losing data" etc).
    There seems to be a 1 to 5% rate of helicity errors in this server
    for unknown reasons which did not occur before the expt.

    2. Modified one line of the ring_map which defines which 4
    channels go to the ring buffer (in addition to clock and helicity
    info). The L1A was redundant with T5 under production conditions,
    so I replaced L1A by Trigger 10. This way one can compute helicity-
    correlated deadtime if that is desirable.

    Previous map

    ring_map[0] = 2; /* trigger 3 */
    ring_map[1] = 17; /* upstream BCM (x3 gain) */
    ring_map[2] = 12; /* L1A (accepted triggers) */
    ring_map[3] = 4; /* trigger 5 */

    Changed ring_map[2] to

    ring_map[2] = 9; /* DVCS trigger 10 */

    ---------------

    These changes will occur the next time you reboot TS11.
