ASIAA CASA Development Center

• ASIAA CASA Development Center (ACDC)
• established on 2016 August 1st.
• in collaboration with NRAO, with the funds of the Ministry of Science

and Technology (MoST)

• Chin-Fei Lee is the ACDC manager
• Currently 6 full time staffs work for ACDC, including one software engineer

lead, three software engineers, one system manager, and one support scientist.

• The number of software engineers is expected to increase to 5 in 2019
• More information can be found from

ASIAA CASA Development Center

• Technical Work Areas
• Development at the ACDC will be fully integrated and coordinated

with the CASA team.

• For the initial year, the ACDC team will augment the effort of NRAO
• n the next generation CASA image viewer; CARTA (Cube Analysis

and Rendering Tool for Astronomy).

• The new CARTA is expected to be out the end of 2018.
• The goal is to replace CASA viewer in CASA.

The CARTA team is now reorganizing the GUI and the underlying architecture, in order to make CARTA more user friendly and easy to manage and add new functionalities. The new CARTA is expected to be out the end of 2018.

Taiwan ARC Node

• established in November 2009, connecting to EA ARC and NA ARC
• working with EA ARC for user support core functions (i.e., P2G, QA2, CS,

Helpdesk, TA, AoD)

• working with NA for enhanced functions
• The 2nd ALMA NA-Taiwan joint workshop in NTHU, Hsin-Chu, Taiwan in 2018 Feb
• Magnetic Fields or Turbulence — which is the critical factor for the formation of stars

and planetary disks?

• currently 9 ARC members
• Yusuke Aso joined from Apr 2017, Yu-Ting Wu moved to NAOJ
• organizing workshops / tutorials on-island in Taiwan, together with

universities in Taiwan

Taiwan ARC Node

• One day CY5 users workshop in

March 2017 to update the status and introduce new capability to the local community

• Support 2017 UCAT ALMA

Summer Student Training Camp to introduce ALMA, radio astronomy, and a broad range

• f research subjects
