Second raw data release

From December 2017 to June 2018 we continued the data acquisition at the ARO 12-m radio telescope. The coverage of survey area is organized in 30’x 30′ square tiles with sides along Galactic axes and a small amount of overlap. Each tile was observed twice in mutually orthogonal scan directions to minimize 1/f noise and eliminate systematics. Figures of the total coverage of the survey area can be found here.

In the download page you will find the second release of raw data, that contains calibrated spectra of single maps. All files are in GILDAS CLASS format and contain the data for each tile for each scan direction independently. The file names are structured as:

tileLLLL-BB_A_SSSS_fbZZ.aro

where:

LLLL are four digits for the Galactic Longitude of the tile center and should be read as LLL...

First data release: raw data

In June 2017 we completed the data acquisition at the ARO 12-m radio telescope.  Observations were carried out from 11/11/2016 to 13/6/2017, for a total of 600 hours. We observed 81 mini maps of size 30″ x 30″ in 12CO (1-0) and 69 in 13CO (1-0). Each tile was observed twice in orthogonal scanning directions to minimize 1/f noise and eliminate systematics. Figures of the coverage can be found here .

All files are in GILDAS CLASS format and contain the data for each tile for each scan direction independently. The file names are structured as:

tileLLLL-BB_A_SSSS_fbZZ.class

where:

  • LLLL are four digits for the Galactic Longitude of the tile center and should be read as LLL.L (so 2244 means GLON 224.4°)
  • BB are two digits for the Galactic Latitude of the tile center and should be read a...

The ARO-FQS Data

This page contains the links to the raw data files made available to the Community soon after they are acquired at the telescope. All files are in GILDAS CLASS format and contain the data for each tile for each scan direction independently. The file names are structured as:

tileLLLL-BB_A_SSSS_fbZZ.class

where:

  • LLLL are four digits for the Galactic Longitude of the tile center and should be read as LLL.L (so 2244 means GLON 224.4°)
  • BB are two digits for the Galactic Latitude of the tile center and should be read as B.B (-12 means -1.2°)
  • A is the scan direction and can have value “l” for scan direction along the Galactic Longitude, or “b” for scan direction along the Galactic Latitude
  • SSSS can have values “12co” or “13co” depending on the species observed
  • ZZ identifies the filterbank u...

The ARO-FQS Survey

The Forgotten Quadrant Survey (FQS) uses the 12-m Kitt Peak antenna of the Arizona Radio Observatory to map the Galactic Plane in the range 220° < l < 240°, in a 2°-latitude strip centered around a midplane that follows the Galactic warp, both in the 12CO (1-0)   and the 13CO (1-0) lines. The project has been awarded 600 hours of observing time under an ESO Call for Proposals, and the data acquisition has started in November 2016.

The FQS survey will provide a much needed complement to latest-generation continuum surveys of the Galactic Plane from the near-mid infrared (GLIMPSE360, WISE) to the submillimeter (Herschel/Hi-GAL) for a portion of the Plane where CO data is currently available only with very low spatial resolution (Dame et al. 2002, Mizuno & Fukui 2004).

The coverage of sur...
