Hiroshi Nagai (NAOJ),

Interim EA-ARC Manager

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

• 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
• pera>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.
