Bob-
    I am in favor of using '0' as the third character, i.e., 'RL0', instead on
a whole code, 'HER'.
    To remain consistent with data already submitted to the PSN, I thought that
it would be easier to preserve the existing station identity as much as
possible while at the same time explicitly specifying that a station code
referred to a station location, and not an instrument. This is also consistent
with a practice that we use with our portable seismographs.
    This is my suggestion.

QED: Quick Epicenter Determination; near-realtime.

PDE: Preliminary Determination of Epicenter; based on data within the few
weeks.

    I will inquire as to what the exact current definitions of QED and PDE are
and whether there is an NEIC station list available.
