SN table uses MP as the reference antenna. Zeroed the rates, since had only one good rate solution for Halca. Good DQA1 solutions existed for Mp-Ho, but not for Halca baselines (except for one solution at the end of the observation). Hopefully, if this one Halca solution is legit, it will enable me to use a small FRING window to find more FRING solutions. #--------------------------------------------------------- #--------------------------------------------------------- {Task} : CLCAL {ADVERBs} : OPCODE = CALP INTERPOL = 'AMBG' REFANT 1 (AT) {Input CL} : 1 {Input SN} : 1 {Output SN} : {Output CL} : 2 {Comments} : #--------------------------------------------------------- #--------------------------------------------------------- {Task} : FRING {ADVERBs} : DOCALIB 1 GAINUSE 2 REFANT 3 (Mp) SEARCH 2 SOLINT 5 APARM(1)=2 APARM(7)=2 (SNR=2) APARM(9)=1 DPARM(0)=3 (no baseline stacking for now) DPARM(2)=200 (200ns delay window!)
