1. Example configuration file
2. Alphabetic command listing & description

eqfilterII is the so called garbage rejector . That is it performs sanity and authoritative region tests to hyp2000arc, loc_global, and/or rayloc messages found on the InRing and passes to the OutRing. InRing and OutRing can not be the same.

All tests are optional. If a test is not configured then it is not performed. If a test is configured then it must pass. Tests are tied to inst_id. More or less all parameters in the hypo summary card may be tested for. Additionally, authoritative regions may be configured. Minimum number of coda picks greater than zero for multiple magnitudes may also be configured. Some tests are specific to message type and are ignored if the message being processed is not of that type. All message types and tests may be configured in a single instance of eqfilterII.

INST_WILDCARD is allowed. If wildcard is the only institute configured for a given test then arc messages from any installation will be tested with those parameters. If only specific installation is configured for a given test, then only messages from that installation will be tested for and all others will fail. If a specific installation is configured for a given test and wildcard is also configured for that test, then messages from the specific will use those parameters, and all other non-specified installations will use the wildcard params.

On startup, eqfilterII reads the configuration file named on the command-line. Commands in this file set up all parameters used in testing events for passing to the clean ring. In the control file, lines may begin with a valid eqfilterII command (listed below) or with one of 2 special characters:

#  marks the line as a comment (example: # This is a comment).
@ allows control files to be nested; one control file can be accessed from another with the command "@" followed by a string representing the path name of the next control file (example: @model.d).
Command names must be typed in the control file exactly as shown in this document (upper/lower case matters!).

1. EXAMPLE CONFIGURATION FILE

# Configuration file for eqfilterII
#
# son of eqfilter
# now reads the following, mutually exclusive message types
#  TYPE_HYP2000ARC
#  TYPE_LOC_GLOBAL
#  TYPE_RAYLOC
#
# pick up messages of specified type, if at least 1 authoritative
# region is defined, extract the lat and lon of the location and the
# installation ID of the author of the  message. Then, using the
# authoritative region polygons, determine whether the location is
# within this installation's authoritative region. If it is not, then
# do not write the message to the OutRing, otherwise the message will
# not get written. Exclude regions are also permitted.
#
# Next, perform all the other optional tests.  If any configured tests
#   fail, do not write message to OutRing.
#
# Except for the authreg test, WildCards are permitted.  If an event
#   logo does not have an instid contained in the list of a particular
#   parameter, then the list is checked for a WildCard.  If there is
#   a WildCard entry, the test is performed.  If WildCard is not
#   configured and the logo instid is not on the list, the message
#   will NOT be written to OutRing (but will be logged if Debut is set).
#
# All tests (including authreg) are optional.  Lack of any configured
#   tests is not tested for (we assume a reasonable level of skill).
#
#
# Note not all tests defined for each message type


LogFile 1     # 0 means don't create a disc log file. 1=> do.
              # 2 means write to module log but not to stderr/stdout

#
# AllowUndefInst - OPTIONAL
#  Applies only to authreg test.
#  If this is uncommented, the TYPE_HYP2000ARC messages with installation
#  ID not listed in any InclRegion command below will be written to the 
#  OutRing.  To prevent writing of messages with "unknown" installation
#  IDs, make sure that this options is NOT commented out.

#
# List authoritative regions: at least one InclRegion keyword is required.
#  It associates an earthworm installation ID with a polygon (max 20 sides)
#  inside of which that installation is authoritative.
#    o An installation can have more than one authoritative region.
#    o A region can belong to more than one installation.
#
# The points of a polygon should be listed as if lines of the polygon
# were being drawn without lifting up the pencil, until the polygon
# is closed. Therefore, the first and the last point should be
# the same, and each two the points in between should be the ends
# of one side of the polygon.
#
# ExclRegion is optional. It allows for "holes" to be cut inside of the 
# authoritative regions defined by InclRegion option.

2. ALPHABETIC COMMAND LISTING & DESCRIPTION

In the following section, all configuration file commands are listed in alphabetical order. Listed along with the command (bold-type) are its arguments (in red) and a description of the command. There are no default values so if you configure the command without arguments, all messages fail.


AllowUndefInst
Command with no arguments and applies only to Authoritative Regions. Any TYPE_HYP2000ARC, TYPE_LOC_GLOBAL, and/or TYPE_RAYLOC messages with installation ID not listed in any InclRegion will pass the Authoritative Region test.

Debug
Command with no arguments. If present, many debug messages are logged.

DepthTest Inst_ID MinDepth MaxDepth
If defined, only messages from Inst_ID that have hypocentral depth between MinDepth and MaxDepth kilometers, exclusive, will be passed. All others fail.

DminTest Inst_ID MaxDmin
If defined, only messages from InstID with a distance to the nearest station of less than MaxDmin kilometers will be passed. All others fail. Hyp2000 only.

ExclRegion  Inst_ID NumSides Lat1 Lon1 Lat2 Lon2 ... Lat1 Lon1
List of exclude regions to cut "holes" in a given Inst_ID's authoritave polygon. The points of a polygon should be listed as if lines of the polygon were being drawn without lifting up the pencil, until the polygon is closed. Therefore, the first and the last point should be the same, and each two the points in between should be the ends of one side of the polygon. INST_WILDCARD is NOT ALLOWED with this test.

GapTest Inst_ID MaxGap
If defined, only messages from InstID with azimuthal gap of less than MaxGap degrees will be passed. All others fail.

GDminTest Inst_ID MaxGDmin
If defined, only messages from Inst_ID with minimum distance in degrees of arc greater than MaxGDmin will pass. All others fail. Not used by Hyp2000.

GetEventsFrom  INST_ID MOD_ID
What message logos to listen to. Can be more than one, but no more than five. The message type is hard coded to TYPE_HYP2000ARC

HeartBeatInt  Seconds
Required command to define number of seconds between heartbeats placed on OutRing.

InclRegion  Inst_ID NumSides Lat1 Lon1 Lat2 Lon2 ... Lat1 Lon1
List authoritative regions. It associates an earthworm installation ID with a polygon (max 20 sides) inside of which that installation is authoritative. An installation can have more than one authoritative region. A region can belong to more than one installation. The points of a polygon should be listed as if lines of the polygon were being drawn without lifting up the pencil, until the polygon is closed. Therefore, the first and the last point should be the same, and each two the points in between should be the ends of one side of the polygon. INST_WILDCARD is NOT ALLOWED with this test.

InRing  RingName 
Read message type HYP2000ARC from this ring.

LogFile  int 
If set to 1, turn on logging. If set to 0, turn it off.

MinMagTest  Inst_ID MinMag
If defined, messages from installation Inst_ID with magnitude greater than MinMag will pass. All others fail.

MaxAVHTest  Inst_ID MaxAVH
If defined, messages from installation Inst_ID with equivalent radius of the horizontal error ellipse greater than MaxAVH km will pass. All others fail. Used by rayloc only.

MaxE0Test  Inst_ID MaxE0
If defined, messages from installation Inst_ID with E0 less than MaxE0 will pass. All others fail. E0 is the value of the largest principal error in kilometers. Not used with global_loc.

MaxERHTest  Inst_ID MaxERH
If defined, messages from installation Inst_ID with ERH less than MaxERH will pass. All others fail. ERH is the value of the largest horizontal error in kilometers. Not used in global_loc.
MaxERZTest  Inst_ID MaxERZ
If defined, messages from installation Inst_ID with ERZ less than MaxERZ will pass. All others fail. ERZ is the value of the veritical error in kilometers. Not used in global_loc.
MyModuleId  name
name is the instance of this module and must be defined in earthworm.d

NcodaTest  Inst_ID MinC Mag

nphTest  Inst_ID NPhase
If defined, messages from installation Inst_ID with more than NPhase arrivals having phase weight greater than 0.1 will pass. All others fail. Not used for global_loc or rayloc messages.

nphtotalTest  Inst_ID NPhaseTotal
If defined, messages from installation Inst_ID with more than NPhase arrivals having phase weight greater than 0.0, or number of phases associated in the case of global_loc and rayloc message, will pass. All others fail.
