Phase I vs. Phase II:

From the full sample of 125 galaxies, 83 will be observed in the 2023B semester in October 2023 to January 2024 (Vz-GAL Phase I; VLA/23B-169). These 83 galaxies primarily lie in the right ascension (RA) 23 hour to 9 hour fields, which can be observed most efficiently at the best observing hours of the day in this semester in the most compact D configuration of the VLA, which offers the best phase stability for these demanding high-frequency observations. The remainder of the sample in the RA 12 and 15 hour fields will be targeted in a future D configuration at different months of the year, when these RA ranges can be covered most efficiently.
