This section of LALApps contains programs that can be used to search interferometer data for inspiral signals using templated matched filtering and associated veto strategies.

Description of the Components of the Pipeline

A short description of each possible part of the inspiral pipeline follows. The more detailed description of each command-line argument can be found in the specific pages for each part of the code.

Template Bank Generation

lalapps_tmpltbank: Calculates the power spectrum and generates a template bank for an analysis chunk of LIGO or GEO data. The bank can be for any of the different kinds of inspiral signals: TaylorF2, BCV etc. The output is written in an aml file.

There is also the capability of outputting the raw data, the response function and the uncalibrated power spectrum in frame files.

Matched Filtering and Injections

lalapps_coherent_inspiral: Takes C data frame files as outputted by inspiral.c for up to 4 detectors and constructs the optimal coherent SNR time series. Triggers are written to an xml file and the time series is written out as a frame file.

Injection Parameter Generation

lalapps_inspinj: Given a mass-file, it generates the mass, distance and time parameters of BNS signals to be injected in the data. It currently generates the signals coming from locations within the galaxies of the Local Group, but the ability to do different distributions will be added soon.

The result is an xml file.

Injection in Frames

lalapps_inspfrinj: Given a frame file with LIGO or GEO data, it injects inspiral signals on the data.

Splitting Large Template Banks

lalapps_splitbank: Given a template bank in an xml file, it splits that bank into smaller banks.
