[daip] CLCAL's opcode 'CALP'

[Teddy Cheung]

Hi Amy, Jim,

I looked at the PC table included in my files and there are bogus phases
for Y1, as expected. PCCOR has no way of telling that these are bogus so
I'm sure it created solutions for Y1 in my SN table. Do I really want to
set Antenna=0 if this is the case? Will CLCAL know I don't want solution
for Y1 applied?
