If the azimuth stacking was selected the following menu appears:

      SELECT OPTION:

The menu should be self explanatory for users familiar with SAFARI, with only the following being particular to PP:

Field 11

specifies the range of the receivers in km.

Field 12

specifies the depth of the receivers in meters.

Field 13

specifies the number of azimuths of the receiver plane for which the response should be computed and stacked.

Field 14

represents a scaling factor which will be applied to all traces. The default is 1.0, i.e. no scaling, but may be changes as desired.

Field 15

represents the parameter to be plotted, with N representing the normal stress or negative pressure in fluids, V the vertical particle velocity and H the horizontal particle velocity. The bracket indicates that only V and H functions are available in the file, and the program will therefore not allow for any other choice.

Field 16

produces the plot with the specified parameters.

Field 17

produces a trace file containing the time series, in file format specified in main menu (default ASCII). The trace file include all the timeseries which would be included in the stacked plot.

Field 19

Returns to main menu for change of e.g. source data, plot format etc.
