view.seis {RSEIS} | R Documentation |
Veiw seismic data (segy) window on an hourly basis.
view.seis(aday, ihour, inkhour, SAVEFILE, days, DB, usta, acomp, STDLAB =c("QUIT", "NEXT", "PREV", "HALF"), TZ=NULL)
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 |
DB |
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") |
TZ |
Number of hours to add to GMT to get local time |
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.
Graphical side effects and save.wpix stores appended picks.
On LINUX systems I wrote these (non-R) programs to set up the data base for segy data:FLS.prl, segydatabase. To get these contact me directly. TZ is (-6) for Guatemala.
