The targets for this survey come from the WISE Catalog of Galactic H II Regions (Anderson et al. 2014, J/ApJS/212/1) and were identified based on mid-infrared and radio continuum emission. In this pilot project, two different configurations of the Compact Array Broad Band receiver and spectrometer system were used for short test observations. The pilot surveys detected RRL emission from 36 of 53 H II region candidates, as well as seven known H II regions that were included for calibration. These 36 recombination line detections confirm that the candidates are true H II regions and allow us to estimate their distances.2017AJ....154...23Bhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/154/23CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+A/171/261 : Radio Recombination Lines of Southern HII RegionsJ/A+A/397/213 : Galactic HII regions (Paladini+, 2003)J/ApJ/653/1226 : Physical properties of galactic HII regions (Quireza+, 2006)J/ApJS/165/338 : Radio recombination lines in HII regions (Quireza+, 2006)J/ApJ/690/706 : Distances of Galactic HII regions (Anderson+, 2009)J/ApJ/738/27 : Galactic HII regions RRL and continuum data (Balser+, 2011)J/ApJS/194/32 : The HII Region Discovery Survey (HRDS).
