Calculates amplitudes on basis of incoming origins and the associated picks.
scamp measures several different kinds of amplitudes from waveform data. It listens for origins and measures amplitudes in time windows determined from the origin. The resulting amplitude objects are sent to the "AMPLITUDE" messaging group. scamp is the counterpart of scmag. Usually, all amplitudes are computed at once by scamp and then published. Only very rarely an amplitude needs to be recomputed if the location of an origin changes significantly. The amplitude can be reused by scmag, making magnitude computation and update efficient. Currently, the automatic picker in SeisComP3, scautopick, also measures a small set of amplitudes (namely "snr" and "mb", the signal-to-noise ratio and the amplitude used in mb magnitude computation, respectively) for each automatic pick in fixed time windows. If there already exists an amplitude, e.g. a previously determined one by scautopick, scamp will not measure it again for the respective stream.
Amplitudes are also needed, however, for manual picks. scamp does this as well. Picks with weight smaller than 0.5 in the corresponding Origin are discarded.
Amplitudes for the following magnitudes are currently computed:
Note that in order to be used by scmag, the input amplitude names for the various magnitude types must match exactly.
scamp inherits global options.
Type: list:string
Definition of amplitude types to be calculated. Default is MLv, mb, mB, Mwp.

Use alternative configuration file. When this option is used the loading of all stages is disabled. Only the given configuration file is parsed and used. To use another name for the configuration create a symbolic link of the application or copy it, eg scautopick -> scautopick2.
Load given plugins.
Run as daemon. This means the application will fork itself and doesn't need to be started with &.
Enable/disable self-shutdown because a master module shutdown. This only works when messaging is enabled and the master module sends a shutdown message (enabled with --start-stop-msg for the master module).
Sets the name of the master-module used for auto-shutdown. This is the application name of the module actually started. If symlinks are used then it is the name of the symlinked application.
Sets the name of the master-username of the messaging used for auto-shutdown. If "shutdown-master-module" is given as well this parameter is ignored.
Time span in hours after which objects expire.
OriginID to calculate amplitudes for and exit.
Dumps the filtered traces to ASCII when using -O.
Verbosity level [0..4]. 0:quiet, 1:error, 2:warning, 3:info, 4:debug
Increase verbosity level (may be repeated, eg. -vv)
Quiet mode: no logging output
Limits the logging to a certain component. This option can be given more than once.
Use syslog logging back end. The output usually goes to /var/lib/messages.
Path to lock file.
Send log output to stdout.
Debug mode: --verbosity=4 --console
Use alternative log file.
Overrides configuration parameter connection.username.
Overrides configuration parameter connection.server.
Overrides configuration parameter connection.timeout.
Overrides configuration parameter connection.primaryGroup.
A group to subscribe to. This option can be given more than once.
Overrides configuration parameter connection.encoding.
Sets sending of a start- and a stop message.
Test mode where no messages are sent.
List all supported database drivers.
The database connection string, format: service://user:pwd@host/database. "service" is the name of the database driver which can be queried with "--db-driver-list".
The configmodule to use.
Load the inventory database from a given XML file.
Do not use the database at all
List all supported record stream drivers
The recordstream source URL, format: [service://]location[#type]. "service" is the name of the recordstream driver which can be queried with "--record-driver-list". If "service" is not given "file://" is used.
Specify a file as record source.
Specify a type for the records being read.
