The program is intended for
suppression in a trace impulse noises.
The program is PEP-client, that is, it is launched from under a shell of batch start-up pktexec, submitting tools under orders of parameters, management of realization and scanning of the protocol of operation of the program.
The setting of parameters and start-up of the program happens from under a shell of batch start-up pktexec. The typical session consists of following steps:
For detailed acquaintance with the user interface of
an environment of batch start, look the description of
the program pktexec. It is given an example windows of an environment with the active panel
of input of parameters below:
Input of the program is the modification of the seismic traces containing impulse noises.
Output of the program is the modification of the edited seismic traces.
The program gets a name of the current project in variable PROJECT. In case of start-up of the program from under a shell, this requirement is fulfilled by a select of the current project.
The program defines a location of the system files of a packet from variable VSPHOME, particular in a profile of the user or in a file setup in a home directory of the user of a packet. In a file setup this variable can appear also under a name VSP.
The program searches for description of parameters in files $VSPHOME/etc/AFSN.pep and $VSPHOME/etc/vsp.pep.
At a home directory of the user there should be a file setup, containing paths to the directories of data, tasks and protocols of transmission of the project, and also paths to the system files of a packet of a VSP. The other requirements are superimposed by a shell of batch start-up
pktexec.
All messages are got out in a standard stream of errors. In case of start-up of
the program from under an interactive shell the messages are maintained in a
file of the protocol of transmission of the task LOG/$PROJECT/SPIN-#.log. The
messages of classes EL_FATAL and EL_ERROR be located after a program
termination in area of the messages of an interactive shell.
The reports of information display in an information line:
The list of codes and identifiers of mistakes (designated below ERROR_IDENT),
beginning with " ERROR __ " is resulted in the document Codes
of mistakes of programs of package UNIVERS.
The diagnostic messages deduced in an information line: "Minimal spike excess above noise level must be greater than 1!" "Quantity of iterations must be less than 6 and greater than 0!" "Couldn't open 'Sxxx' modification of input traces due to ERROR_IDENT." "Can not create 'Sxxx' modification for edit traces due to
ERROR_IDENT." Interaction with other programs.
Description.
Session.
Parameters of processing.
Directive parameters (panel Parameters).
The type: nmod_s
Description: the Input modification of traces for editing.
The type: float2
Description: the Range of cable depths for processing.
Outside of this range traces are not processed, but
writing in an output modification. The traces getting in this range,
are editing.
The type: float
Description: the Minimal excess of peak over an average level of noise.
Value of parameter should be more than 1.
Recommended value of parameter 3.
The type: float2
Description: the High-frequency filter for suppression of a signal.
The filter is set by two frequencies: the first specifies the beginning of a slope of the filter, the
second specifies the end of a slope of the filter.
The type: int
Description: Quantity of iterations for determining of parameters of a noise.
Allowable values from 1 up to 5.
Recommended value of
parameter 3.
The type: nmod_e
Description: the Output modification of the edited traces.
Information of a burn-time of the program (panel Runtime).
The type: string
Description: the Information line displaying a stage of work of the program.
The type: progress
Description: Shows a share of the edited traces.
The type: float
Description: Shows the current cable depth.
The type: int
Description: Shows logic number of the magnitogram of the current trace.
The type: int
Description: Shows quantity of the found impulse noises in the current trace. Parameters of results (panel Results).
The type: nmod_s
