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 Scienceand 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 supportscientist.

•The number of software engineers is expected to increase to 5 in 2019

Technical Work Areas•

Development at the ACDC will be fully integrated and coordinatedwith the CASA team.

•For the initial year, the ACDC team will augment the effort of NRAO
on the next generation CASA image viewer; CARTA (Cube Analysisand 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 underlyingarchitecture, in order to make CARTA more user friendly and easy tomanage and add new functionalities. The new CARTA is expected tobe 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)
