The HI/OH/Recombination line survey of the inner Milky Way (THOR)

The THOR project mapped observations of the HI 21 cm line, four OH lines, nineteen Hnα radio recombination lines as well as the continuum emission from 1 to 2 GHz in full polarization over a large part of the first Galactic quadrant, using the Karl G. Jansky Very Large Array (VLA) in the C-array configuration. The first release of the THOR data covered observations for l = 14.0 - 37.9, and l = 47.1 - 51.2, |b| < 1.25. The second release provided observations of the whole survey (l = 14.0 - 67.4 and |b| < 1.25), combining VLA C+D+GBT (VLA D-configuration and GBT data are from the VLA Galactic Plane Survey, Stil et al. 2006).

CADE currently provides the HI integrated intensity map (without continuum) at the 40 arcsec angular resolution, in units of Jy/beam.Km/s, and continuum emission maps at 1060, 1310, 1440, 1690, 1820 and 1950 MHz at the 25 arcsec angular resolution, in units of Jy/beam.
