PLOTTS PLOTs the Time Series used in or created by a * SPARC*
.

If there is a single receiver depth, the horizontal axis is time and the vertical axis is amplitude.

If there is more than one receiver depth the each receiver time series is shifted vertically in accordance with the receiver depth.

FREQ FMIN FMAX PULSE 0.0 1.5 0.5 / ! TMIN TMAX TINC (s) TAXL (cm) -1.0 1.0 1.0 / ! YMIN YMAX YINC (m) YAXL (cm) (1) - FREQUENCY SPECTRUM / PULSE INFORMATION: Syntax: FREQ FMIN FMAX PULSE Description: FREQ: Characteristic frequency (Hz). This is only used for those canned signals defined by a characteristic frequency. FMIN: Low cut frequency (Hz) FMAX: High cut frequency (Hz). PULSE(1:1): Signal type 'P' Pseudo-Gaussian 'R' Ricker wavelet 'A' Approximate Ricker wavelet 'S' Single sine 'H' Hanning weighted four sine 'N' N-wave 'G' Gaussian 'F' From an '.STS' (Source Time Series) file. 'B' From an '.STS' file Backwards PULSE(2:2): Hilbert transforming. This is used to eliminate the left travelling wave. 'H' perform a Hilbert transform of the signal 'N' don't PULSE(3:3): Signal sign flipping. '+' don't flip it '-' flip it PULSE(4:4): signal filtering. 'L' low cut filter 'H' high cut filter 'B' both high and low cut filter 'N' no cut (2) - TIME AXIS INFO Syntax: TMIN TMAX TINC TAXL Description: TMIN: First time (s ). TMAX: Last time (s ). TINC: Time interval for tick marks (s ). TAXL: Time axis length (cm). (3) - VERTICAL AXIS INFO Syntax: YMIN YMAX YINC YAXL Description: YMIN: Y minimum (m ). YMAX: Y maximum (m ). YINC: Y interval for tick marks (m ). YAXL: Y axis length (cm). If there is only one time series to plot then YMIN, YMAX should normally be -1, 1. If there are multiple time series corresponding to different depths or ranges then YMIN, YMAX should normally be the max and min depths or ranges.
