GASS HI Spectra


Here you can download GASS HI spectra in 2 formats: ASCII or FITS. The links below allow you to download each data release (tar.gz files); detections and non-detections are kept separated for convenience.

The HI spectra are calibrated, smoothed and baseline-subtracted. For each galaxy, the file contains header information and the following data columns: 1. Heliocentric velocity [km/s]; 2. Radio frequency [MHz]; 3. Flux Density [mJy]; 4. Subtracted polynomial baseline fit [mJy].

If you use the data products presented here, we would appreciate an acknowledgement in any publications which result. Thanks!
