Abstract:
The ALMA 12m observations consist of one execution block (EB) conducted during Cycle 5 on 4 October 2017 (project ID: 2017.1.00098.S - PI: Maud) in configuration C43-10, with 43 antennas. The on-source time was 30.6minutes. Here we provide the continuum map of G17.64+0.16 before and after the removal of a point-source (that accounts for the free-free contamination. A possible maximal and minumal value are used. We also provide the image cubes for H20, SIO, and H30alpha. The resulting resolution of the continuum images made with robust=0.0 was 20x15mas. For the H20 line robust=1.5 was use and the resulting resolution was 28x23mas. The SIO map also used robust=1.5 and has a resolution 30x24mas, while the H30alpha used robust=0.0 and has a resolution 20x18mas. All data use the ALMA 12m main array with the long baseline configuration C43-10. All data are selfcalibrated with the pointing centre shifted to be centred on G17.64+0.16.
