Extragalactic HI survey with FAST : First look of the pilot survey
  results
  As first data release of a pilot extragalactic HI survey with
Five-hundred-meter Aperture Spherical radio Telescope (FAST),we extracted 544
extragalaxies from three-dimensional(3D) spectral data to perform interactive
searching and computing, yielding global parameters for these detections,
extending redshift ranges of HI 21cm line up to z = 0.04 ,which covers part of
the sky region in right ascension(R.A. or $\alpha$) and declination(Dec or
$\delta$) range $00^{\rm h} 47^{\rm m}< \rm R.A.(J2000)<23^{\rm h}22^{\rm m}$
and $+24^{\circ}<\rm Dec.(J2000) <+43^{\circ}$ . The S/N of 544 HI detections
are greater than 5 flagged with code 1 to 4 based on baseline qualities or RFI
contamination. Besides, we find 16 of which without any counterparts in the
existing galaxy catalogs. The catalog can give a guidence for the future HI
observation with FAST.
