The Data Analysis Software Working Group (DASWG) of the LIGO Scientific Collaboration is responsible for the development, of data analysis software. The working group is open to all LSC members who are interested. DASWG holds regular and frequent membership meetings, both by telecon and at LSC meetings. It has a Chair, named by the LSC Spokesperson. One distinctive structural feature is the existence of a steering committee, the Data Analysis Software Committee, chaired by the working group Chair. The role of the Steering Committee is to broker consensus on issues where discussions of the general membership have been unable to find consensus.

Weekly telecon

The working group holds a weekly telecon at 11:00 Pacific time every Tuesday. Dates and dial-in instructions are posted under Participate > Telecon; the agenda and minutes of each meeting are posted at Docs > Minutes
