NON_LIN_LOC

Default pick format from NonLinLoc (see: http://alomax.net/nlloc -> Formats -> Phase Files -> NonLinLoc Format)

NonLinLoc phase record description:

Station name (char) - station name or code

Instrument (char) - instrument identification for the trace for which the time pick corresponds (i.e. SP, BRB, VBB)

Component (char) - component identification for the trace for which the time pick corresponds (i.e. Z, N, E, H)

P phase onset (char) - description of P phase arrival onset; i, e

Phase descriptor (char) - Phase identification (i.e. P, S, PmP)

First Motion (char) - first motion direction of P arrival; c, C, u, U = compression; d, D = dilatation; +, -, Z, N; . or ? = not readable.

Date (yyyymmdd) (int*6) - year (with century), month, day

Hour/minute (hhmm) (int*4) - Hour, min

Seconds (float) - seconds of phase arrival

Err (char*) - Error/uncertainty type; GAU

ErrMag (expFloat) - Error/uncertainty magnitude in seconds

Coda duration (expFloat) - coda duration reading

Amplitude (expFloat) - Maxumim peak-to-peak amplitude

Period (expFloat) - Period of amplitude reading

PriorWt (expFloat) - A-priori phase weight Currently can be 0 (do not use reading) or 1 (use reading).
