Hi Cormac, I've attached the ASKAP pad locations. As far as I can tell the intended rollout program is/was: Sequence Number Antenna Number Comment 1 5 2 4 3 2 4 12 Array Release 1 – First Image 5 14 6 13 Array Release 1a – Early Science Pilot 7 10 8 16 9 24 10 30 11 28 12 25 Array Release 2 – Early Science 13 27 14 17 15 26 16 18 17 34 18 19 Array Release 3 – Pawsey On-Line Processing 19 20 20 22 21 8* 22 23 23 1* 24 3* 25 6* 26 9* 27 15* 28 36 29 32 30 33 Array Release 4 –Construction Project Complete 31 7 32 11 33 21 34 29 35 31 36 35 ASKAP Complete to Full Specs. I think the arrays to include would be at least ASKAP-12, ASKAP-36, possibly ASKAP-18 and ASKAP-30. We're currently at ASKAP 12, but in practice broken antennas get swapped with working ones from the ever increasing set of fully installed ones. Cheers, Mark
