¥Concept began about 11 years ago (1998)
¥NRAOÕs Ray Escoffier was busy with ALMAÕs correlator - could not commit to EVLAÕs also
¥Canada needed an ÔinÕ into ALMA (a share in its use)
¥Rick Perley contacted Peter Dewdney of DRAO, Penticton, BC, Canada; they go back to college days
¥Peter, after much effort, got funding ~$25M by the Canadian Government to supply the correlator in return for access to NRAO antennas including our share in ALMA.
¥Primary architect of WIDAR is Brent Carlson of DRAO
¥Hardware was built in Canada
¥Software is being developed as a joint effort between NRAO and DRAO.
