VizieR Online Data Catalog: Ionization profiles of 8 Galactic H II regions (Luisi+, 2019)
Abstract
We observed eight HII regions with the Green Bank Telescope (GBT) from 2017 February to 2017 May. The properties of the observed HII regions are given in Table 1.
The individual pointings for each observed HII region lie along an imaginary line on the plane of the sky intersecting the region center. The angle of the line was chosen such that there is as little confusion by other radio sources (e.g., nearby HII regions) as possible. For each targeted HII region, between 7 and 17 positions were observed. The locations of the observed positions for each source are shown in Figure 1. The coordinates of all observed directions are given in Table 3. The GBT C-band instantaneous bandpass in combination with the Versatile GBT Astronomical Spectrometer (VEGAS) backend includes 22 Hnα lines, 19 Hnβ lines, and 8 Hnγ lines between 4.054 and 7.793GHz.
