Available Data
SIGNALS will ultimately include data for 36 fields of a potential target list of about 60 galaxies, easily containing 50,000 HII regions in total.
Our aim is to release catalogs, images, and spectra for all our sources. The catalogs will include flux maps, velocity dispersions, signal-to-noise ratios, HII region identification, and parameters such as sizes, luminosities, masses, extinction, etc., and their associated uncertainties.
Below is a table of potential targets with some basic information taken from the NASA Extragalactic Database. An observed column is also provided showing the status of observations for a particular galaxy. For more up-to-date information, check out the News page.
