| a |
Designate first arrival in header {1,7}. |
| b |
Display previous plot (if there is one). |
| c |
Evaluate first arrival and end of event {1,4,7}. |
| d |
Set phase direction to DOWN (precedes P or S phase pick). |
| e |
Set phase onset to EMERGENT (precedes P or S phase pick) |
| f |
Define end of event {1,2,3,7}.. |
| g |
Display picks to terminal in HYPO format {4}. |
| h |
If CHPF precedes call to PLOYPK, write picks to HYPO pick file {3,4}. |
| i |
Set phase onset to IMPULSIVE (precedes P or S phase pick). |
| j |
Set noise level {2,6,8}. |
| l |
Saves and lists x and y values for cursor location {2,4}. |
| m |
Compute maximum amplitude waveform {2,3,5}. |
| n |
Display next plot (if there is one). |
| o |
- Zoom Out => Displays previous plot window.
- A maximum of five windows are saved.
|
| p |
Designate P wave arrival time {1,2,3,7}. |
| q |
Terminate PLOTPK immediately. |
| s |
Designate S wave arrival time {1,2,3,7}. |
| t |
- Designate user time Tn in header {1,2,7}.
- Next keystroke should be an integer between 0 and 9.
|
| u |
Set phase direction to UP (precedes P or S phase pick). |
| v |
Define a Wood-Anderson waveform {2,5}. |
| w |
Define a general waveform {2,5}. |
| x |
- Set Zoom window
- Set beginning of zoomed plot
- If x is second keystroke, set end of zoomed window and display
- If s is second keystroke, defined zoomed plot limits are saved
and used as xlims for subsequent plots
|
| z |
- Set zero (reference) level {2,6,8}. If reference is on with a value
- f, two more horizontal lines are drawn at +/- f from the z line.
|
| '+' |
Set phase direction to PLUS (precedes P or S phase pick). |
| '-' |
Set phase direction to MINUS (precedes P or S phase pick). |
| ' ' |
Set the phase direction to NEUTRAL (precedes P or S phase pick). |
| 'n' |
Set phase quality to n, n=0,1,2,3, or 4. (precedes P or S phase pick) |
