Blind Survey
HIPASS
- The HI Parkes All-Sky Survey (HIPASS) covered 30000 deg2 and produced a final catalog of around 5000 HI detections with a median redshift of 2800 km/s.
ALFALFA
- Arecibo Legacy Fast ALFA Survey (ALFALFA) will map 7000 deg2 and is expected to detect more than 25,000 extragalactic HI
line sources out to redshifts of 18,000 km/s.
Galaxy
AGES
- Arecibo Galaxy Environment Survey (AGES), will cover a total area of 200 deg2 (divided into 13 predesignated regions to sample different environments) to greater depth
THINGS
- The H I Nearby Galaxy Survey (THINGS)," a high spectral (≤5.2 km s–1) and spatial (~6) resolution survey of H I emission in 34 nearby galaxies obtained using the NRAO Very Large Array (VLA).
- public data [1]
NIBLES
- Nançay Interstellar Baryons Legacy Extragalactic Survey (NanCay Radio Telescop 100m)
- Must have both SDSS magnitudes and optical spectrum;
- Must lie within the local volume (900<cz<12,000 km s−1);
- Uniform sampling of each 0.5 magnitude wide bin in absolute z-band magnitude, Mz;
- Preferentially observe nearby objects;
- No a priori selection on color.
