			Here is the detailed procedure:

			start with some bright cal, Hmag < 4, and size ~0.4mas. VEGA needs to do some alignment first, then MIRC can do fiber explorer.
			Then MIRC take over the control of delat carts to find all fringes just as what we usually do alone. Write down the offsets. Then VEGA
			will take over the control of delay carts, and find fringes alone, write down the VEGA offsets. Then MIRC take over the control again,
