--LAT N--

DEPTH/KM Hypocenter depth jn km.
N/RD Number of P & S readings with weights larger than 0.1.
N/S Number of S readings with weights larger than 0.1.
RMS/SEC The root-mean-square travel time residual, in sec, using all weights.
ERH/KM The horizontal location error, in km, defined as the length of the largest
projection of the three principal errors on a horizontal plane.
The principal errors are the major axes of the error ellipsoid, and
are mutually perpendicular. ERH thus approximates the major axis
of the epicenter's error ellipse.
ERZ/KM The depth error, in km, defined as the largest projection of the three
principal errors on a vertical line.
LOC/REMKS The first remark is the 3-letter region code based on location and
depth. Two auxiliary 1-letter remarks (F for felt, etc.) may be
derived from an optional remark field in the phase data (see phase
data input format above). A (#) indicates convergence
problems with the final solution such as running out of iterations,
or failure of the hypocenter to reach a minimum in RMS. A minus
sign (-) indicates the depth was held fixed either by the user or
by insufficient data.
PREF/MAG Preferred magnitude, followed by 1-letter magnitude-type code (see MAGS below)
N/RD Number of observations, expressed as the total of their weights, used to
compute the magnitude
AZ/GAP The largest azimuthal gap between azimuthally adjacent stations (in degrees).
MIN/DS Distance to the nearest station (in km).
N/FM Number of first-motion readings
CRU/MOD Name of velocity model used for computing earthquake location
S./PF The most common data source of the (P) traveltime and (F) first-motion data
N/VR Number of valid P & S readings (assigned weights larger than 0).
DUR/MAG Coda duration magnitude computed from high-gain vertical components.
Value is computed from weighted median of individual station duration magnitudes
NUM/DUR Number of coda durations used in the computing median duration magnitude given
as the total of their weights.
MAGS-N Additional magnitudes for this event. Format is Mx=M_#, where
Mx=type of magnitude, and
x=E=Energy magnitude
L=Local magnitude as computed by UC Berkeley
W=Moment magnitude
X=S-wave maximum amplitude magnitude
Z=Low gain (Z component) coda duration magnitude of Hirshorn and Lindh (1989).
M =magnitude value
# =Number of observations, given as the total of their weights, used in computing M
