Science Opera>on in past ~1 yr • Cycle 4 opera>on: Oct. 1, 2016 – Sep. 30, 2017 • Several New Capabili>es • Large program • Spectral line polarimetry • Solar observa>ons • VLBI observa>ons • ACA standalone • 109 Grade A+B projects, 49 Grade C projects in EA • New challenge: improving delivery efficiency was the biggest concern as the delivery backlog was becoming significant • Cycle 5 opera>on: Oct. 1, 2017

Cycle 4 Performance • Antenna numbers were in line with expecta>ons • Available hours fell ~8% short due to weather down>me • Project comple>on fell short of expecta>ons due to June-September queue mismatch caused by the change in the configura>on schedule • Poor queue match to the sky led to some devia>ons in execu>ve balance that need to be recovered in Cycle 5

Data Delivery Progress FullyObserved - Delivered MOUSs Number of FullyObserved and Delivered MOUSs

Data Delivery Progress • Situa>on is gejng much improved • Both pipeline calibra>on and imaging are in opera>on at EA- ARC. • Pipeline flagging and low SNR heuris>cs are mostly successful • Data reducer do not quite olen need to do manual interven>on. • Automa>c queueing of pipeline calibra>on and imaging will be opera>onal soon.

What’s New in Cycle 5 Opera>on? • P2G: PIs not genera>ng SBs in Cycle 5, just revising SGs and submijng their projects again for confirma>on. Observatory genera>ng automa>cally SBs, then reviewed by ARC staff. • Helpdesk: PI can trigger ToO observa>ons via helpdesk and directly contact the staff in Chile. • Archive: All the archive contents have unique file names e.g., scriptForPI.py -> member.uid___A002_Xabc_X0123.scriptForPI.py

Cy5 Configura>on Schedule

New Delivery Style in Cycle 5 • No single tar package is archived anymore. • Download individual files • README txt is replaced by AQUA QA2 Report

Ques>on to all of you • According to the user survey, user sa>sfac>on rate for informa>on about proposal prepara>on (Proposing Guidance page in SP) was significantly low in EA. • We kindly ask you to provide us your sugges>on in discussion session.
