checkLOCATEinput: Check Location data

In Rquake: Seismic Hypocenter Determination

Description

Check to see if location data has the minimally correct list components.

Usage

checkLOCATEinput(Ldat, EQ, vel = NULL)

Arguments

Ldat	list, must inlude: x,y,err, sec, cor (see details)
EQ	list, must inlude: x,y,z, t
vel	list, 1D velocity structure

Details

Input pick list must have at x,y,z, sec, cor, err elements for each station.

Value

logical: FALSE mean problem with data
