cwb_eced¶

This page provides a description of the cwb_eced command.

Usage

This command generates the CED of an event via command line (easy CED).

Syntax

cwb_eced (no arguments)

Prints help

cwb_eced eced_opts [detector_opts]

Generates the CED via command line

Further information

The following options can be passed to the cwb_eced command:

eced_opts =   gps_time    :  this is the GPS time of the event

             or

             '--gps gps --search search --sim sim --tag tag --cfg cfgfile'

             In the above line, the various options have the following meaning:
             --gps is the GPS time of the event
             --search is the search type (r, i, s, g, R, I, S or G for the 1G pipeline, r for the 2G pipeline)
             --tag is a label used to name the directory in which the CED is generated. If the tag is not
                   specified, the default tag is used (corresponding to the current GPS time).
             --cfg is the name of the configuration file. The default configuration file used to generate
                   the easy CED is trunk/tools/cwb/macros/cwb_parameters.C. To chage the default values,
                   add the desired parameter values in a new file cfg.C and use the option --cfg cfg.C
             --ced false : disable CED, only root file is created


detector_opts =  '--ifo ifo --type type --chraw chraw --chmdc chmdc --factor factor'

             In the above line, the various options have the following meaning:
             --ifo is the detector name. If the gw_data_find tool is used, the input must be one
                   of the following: L1, H1, V1, G1
             --type is the type which identifies the considered detector's data. It the same as the one used
                    by the gw_data_find tool. The following command lists the available types:
                    gw_data_find -y. Alternatively, the type can be the name of the file containing the list of
                    the considered frame files. Note that the name of this file must be of the format yyy.xxx .
                    If no type is defined, the following default values are used:
                           L1 -> L1_LDAS_C02_L2
                           H1 -> H1_LDAS_C02_L2
                           V1 -> Hreconline
                           G1 -> G1_RDS_C01_L3
             --chraw is the name of the channel to be read in the frame files. If no channel is defined,
                    the following default values are used:
                           L1 -> L1:LDAS-STRAIN
                           H1 -> H1:LDAS-STRAIN
                           V1 -> V1:h_16384Hz
                           G1 -> G1:DER_DATA_H
             --chmdc is the name of the mdc frame channel
             --factor is the numerical factor used to rescale the hrss or the snr of the injected simulated signal
             --shift is the detector shift time in seconds for non zero lag events (NOTE : must be integer!!!)

The cwb_eced command creates a directory named according to the following format:

ECED_net_TAGtag_GPSgps

where

net corresponds to the considered network (e.g., L1H1V1)

tag is part of the name of the directory in which the CED is saved, see above in this page.

gps is the GPS time of the considered event

An example of the directory’s name is as follows:

ECED_L1H1V1_TAG1048593634_GPS968654557

The following sub-directories are created in the main folder:

tmp: this directory contains temporary files

ced: this directory contains the CED of the event.

A symbolic link is created in the user’s public directory to make the CED accessible via a web browser, e.g.:

~waveburst/WWW/LSC/ceds/ECED_L1H1V1_TAG1048593634_GPS968654557

Note that the cwb_eced command cannot be used in the simulation mode.

Note

if “-ced false” is declared then only the standard wave*.root is created.
