Survey of Ionized Gas of the Galaxy, Made with the Arecibo telescope (SIGGMA) inner galaxy data release. (2019)

Keywords : catalogs ; H II regions ; radio lines ISM ; surveys

Abstract:The Survey of Ionized Gas of the Galaxy, Made with the Arecibo telescope (SIGGMA) provides a fully sampled view of the radio recombination line (RRL) emission from the portion of the Galactic plane visible with Arecibo. Observations use the Arecibo L-band Feed Array, which has a FWHM beam size of 3.4'. Twelve hydrogen RRLs from H163{alpha} to H174{alpha} are located within the instantaneous bandpass from 1225MHz to 1525MHz. We provide here cubes of average ("stacked") RRL emission for the inner Galaxy region 32{deg}<=l<=70{deg}, |b|<=1.5{deg}, with an angular resolution of 6'. The stacked RRL rms at 5.1km/s velocity resolution is ~0.65mJy/beam, making this the most sensitive large-scale fully sampled RRL survey ...(more)

We described the observations and data reduction in full in Paper I (Liu+ 2013AJ....146...80L). We used the seven-beam Arecibo L-band Feed Array (ALFA) receiver for the Survey of Ionized Gas of the Galaxy, Made with the Arecibo telescope (SIGGMA) observations. The observations started in 2010. The receiver has a bandwidth of 300MHz, covering 1225-1525MHz.
