view.seis: Veiw seismic data window

Description

Veiw seismic data (segy) window on an hourly basis.

Usage

view.seis(aday, ihour, inkhour, SAVEFILE, days, DB, usta, acomp,  STDLAB =c("QUIT",  "NEXT", "PREV", "HALF"), TZ=NULL)

Arguments

aday

index of which day to use in vector days

ihour

hour to start

inkhour

increment in hours for viewing panel

SAVEFILE

file to save window picks in

days

vector of days to select from

data base list of file names and start-times and durations

usta

stations to select

acomp

compnents to select

STDLAB

vector of buttons, DEFAULT = c("QUIT", "NEXT", "PREV", "HALF", "WPIX", "zoom out", "refresh", "restore", "SPEC", "SGRAM" ,"WLET", "FILT", "Pinfo", "WINFO")

Number of hours to add to GMT to get local time

Value

Graphical side effects and save.wpix stores appended picks.

Details

The program view.seis assumes the data is stored in files accessable by the user and that the DB list has been scanned in and parsed.

Examples

Run this code

##############  method one:
#######  read in data base from files:
DB  = scan(file="/home/lees/Site/Santiaguito/SG09/segyDB", list(fn="",
yr=0, jd=0, hr=0, mi=0, sec=0, dur=0))

##  this file has first line:

#c...|....1....|....2....|....3....|....4....|....5....|....6....|....7.$

##  note: the file name includes the station SMI and the component J
