Cycle 5: observations
- Cycle 5: October 2017
– September 2018
- Antenna numbers –
consistently higher than 42
- Observing efficiency
>85% in May, July and September
- 12-m time: 5% short
- f 4000 hours
– the winter weather
- Good weather, but lack
- f high frequency

Cycle 5: data delivery
- Data obtained since March 1st 2018
– Pipeline: 90% of the data were delivered in 21 days – Manual: 90% of the data were delivered in 61 days

Goal:
– Pipeline: 30 days – Manual: 45 days

Cycle 5/6: Recent status
- 66 antennas were used in Cycle 6!
- A few problems at the beginning of
Cycle 6
- Raw data delivery pilot program
– Out of 59 selected programs with 106 MOUSes, the PIs of 14 programs (5 in EU, 4 in EA, and 5 in NA) agreed on participating. This low fraction, 24%, reflects the successful data delivery times.

Cycle 5/6: Recent status
- ACA observatory filler programs for Cycle 5Cycle
– Four filler programs with the ACA. – The programs were designed to fill a gap in the ACA
- bserving schedule in the remainder of Cycle 5
between LST of 22 and 1.5 h. – The programs were selected based on input from scientists at the Joint ALMA Observatory (JAO) and the ALMA Regional Centers (ARCs). The proposed programs were reviewed by the ALMA Integrated Science Team (IST) with final approval by the ALMA Director. – The data are released through the ALMA Archive with no proprietary period. Observations may not be complete due to the low priority.

Cycle 5/6: Recent status
- CASA mosaic imaging issue
An announcement on October 16, 2018
(Also in the Science portal: https://almascience.nao.ac.jp/)
– Mosaic with 7-m array in Cycle 1-4
- Fluxes are overestimated by ~10%
– Mosaic in Cycle 5
- Degree of effect depends on the images
- Proprietary time is paused retroactively to July 2018
- The data are now in the state of QA3, users cannot
download the data.
– The problem is solved with CASA 5.4

Cycle 7
- 1. Main call: October 2019 – September 2020
- 2. Supplemental call for ACA stand-alone:
January 2020 – September 2020 Pre-announcement has been issued. → Nagai-san’s presentation
