One Phase Pick Per Station

Description

Require only one pick per station of a specified phase.

Usage

OnePerSta(twpx, phase = "Y")

Arguments

twpx

WPX list

phase

character, specific phase

Details

This is used to reduce the number of picks for specific station and phase. The purpose is avoid multiple P-wave phases for each station in the earthquake location routines.

Value

WPX list

Note

For S-waves there may be multiple S-wave arrivals, as in the case for shear wave splitting. In that case it is probably best to name the phases differently, as in S1, S2, for example.

Examples

s1 = RSEIS::setWPX(name="HI", phase="P", yr=2011, jd=231, hr=4, mi=3, sec = runif(5)) 
s2 = RSEIS::setWPX(name="BYE", phase="P", yr=2011, jd=231, hr=4, mi=3, sec = runif(5)) 

s3 = RSEIS::catWPX(s1, s2)

s4 = OnePerSta(s3, phase = "P")
