File : ant_clock.y Updated : 23apr95 by mclaussen 24apr95 by mclaussen Note: Since the Odetics GPS receiver at the VLA was removed and sent to HN, and has yet to be replaced, we can, at least temporarily, no longer use the GPS time to estimate the clock offset at the VLA. The clock offsets below are estimated using the counter at the VLA that measures the difference between the Trak GPS receiver and the L108 formatter clock. We should make correlator jobs with these numbers and then run a trial production.
