Pick Toolbar

Display time and amplitude values and make picks for the active trace.
_______________________

Hold down the left mouse button and drag the mouse horizontally to move the pick cursor.

Drag the mouse vertically to change the pick uncertainty (*).

Press the right mouse button to activate pop-up menu for registering the pick or setting the pick label.

Press the left mouse button over an existing pick label to re-activate and remove or edit an existing pick.

(NOTE: Saved or modified picks are immediately saved to the pick file.)
_______________________

"Clear" - clear the selections for the current pick

"e i" (*) - select onset (e = emergent; i = impulsive)

"P S CODA ..." - select reading name (P, S, CODA, ...), or enter name

"c d" (*) - select first motion (c = compression or up; d = dilatation or down)

"0 1 2 3 4" (*) - select quality (0 = best, max weight; 4 = worst, zero weight)

"Set" - register the current pick time, amplitude and label, and save to file (if a pick file is open)

"DelAll" - remove all picks for active trace-group and delete from file (if a pick file is open)

"DelPrevious" - remove previously set pick for active trace-group and delete from file (if a pick file is open)

"0-P_max" - auto pick of point on seismogram with maximum 0 - peak amplitude difference

"P-P_max" - auto pick of point on seismogram with maximum peak - peak amplitude difference

"PeakWin" - convert each trace to absolute value of peak amplitude in sliding window of specified half-width before each data point

"Sta/Lta Tool" - apply a basic STA/LTA picker to all traces in active trace-group

"Apply" - calculate with the current settings

"ST Window: <nnn>" - short term average window width (seconds)

"LT Window: <nnn>" - long term average window width (seconds)

"Trigger Ratio: <nnn>" - trigger ratio - value of STA/LTA to declare a trigger

"Direction: FORWARD | BACKWARD" - processing direction in time

"Result: PICKS | TRIGGERS | STA/LTA" - display results as new SeisGram2K picks on existing traces, or as new trace showing triggers or STA/LTA ratio

"BK Picker" - apply a Baer-Kradolfer picker to all traces in active trace-group

(M. Baer and U. Kradolfer, (1987), An automatic phase picker for local and teleseismic events Bull. Seism. Soc. Am., 77(4):1437-1445)

"Apply" - calculate with the current settings

"Threshold1: <nnn>" - Threshold1 value from Baer and Kradolfer, 1987

"Threshold2: <nnn>" - Threshold2 value from Baer and Kradolfer, 1987

"tUpEvent: <nnn>" - tUpEvent value from Baer and Kradolfer, 1987

"tDownMax: <nnn>" - tDownMax value from Baer and Kradolfer, 1987

"Direction: FORWARD | BACKWARD" - processing direction in time

"Result: PICKS | CHAR_FUNC | TRIGGERS" - display results as new SeisGram2K picks on existing traces, or as new trace showing characteristic function values or triggers

"FP5" - apply Filter Picker to all traces in active trace-group

(A. Lomax, C. Satriano and M. Vassallo (2012), Automatic picker developments and optimization: FilterPicker - a robust, broadband picker for real-time seismic monitoring and earthquake early-warning, Seism. Res. Lett. , 83, 531-540, doi: 10.1785/gssrl.83.3.531.)

"Apply" - calculate with the current settings

"FiltWin: <nnn>" - Filter Window value from Lomax et al., 2012

"LTWin: <nnn>" - Long-Term Window value from Lomax et al., 2012

"Thres1: <nnn>" - Threshold1 value from Lomax et al., 2012

"Thres2: <nnn>" - Threshold2 value from Lomax et al., 2012

"tUpEvent: <nnn>" - tUpEvent value from Lomax et al., 2012

"Result: PICKS | CHAR_FUNC | TRIGGERS" - display results as new SeisGram2K picks on existing traces, or as new trace showing characteristic function values or triggers
_______________________

"Cumul" - auto pick of first point where amplitude is fraction f of maximum value; see pick.cumulative parameters
_______________________

Peak Extractor tool: find and set pick for one or more peaks on active trace

"Apply" - calculate with the current settings

"Max Num Peaks: <nnn>" - only first <<nnn>> peaks with largest amplitude will be picked

"Min Amplitude: minAmplitude" - only peaks with amplitude >= minAmplitude * maximumPeakAmplitude will be picked
