The LSC Algorithm Library Suite (LALSuite) is comprised of various gravitational wave data analysis routines written in C following the ISO/IEC 9899:1999 standard, more commonly referred to as C99.
LALSuite is comprised of the following components:
- LAL: Core gravitational wave analysis routines
- LALFrame: LAL wrapping of the LIGO/Virgo Frame library
- LALMetaIO: LAL wrapping of the MetaIO LIGO_LW XML library
- LALSimulation: LAL routines for gravitational waveform and noise generation
- LALBurst: LAL routines for burst gravitational wave data analysis
- LALInspiral: LAL routines for inspiral and ringdown CBC gravitational wave data analysis
- LALInference: LAL routines for Bayesian inference data analysis
- LALPulsar: LAL routines for pulsar and continuous wave gravitational wave data analysis
- LALApps: Collection of gravitational wave data analysis codes and pipelines utilising the LAL libraries
The documentation for all LALSuite components is generated using Doxygen. The most recent LALSuite documentation from the nightly build can be found here
The LAL Specification and Style Guide
document (commonly known as the LAL Spec
) contains the software specifications that code written for LALSuite should conform to. The most recent version of the LAL Spec
can be found here
