A search for Low Surface Brightness galaxies in the near-infrared. III. Nancay HI line observations. Monnier Ragaigne D., van Driel W., Schneider S.E., Balkowski C., Jarrett T.H. <Astron. Astrophys. 408, 465 (2003)> =2003A&A...408..465M
ADC_Keywords: Galaxy catalogs ; Galaxies, photometry ; Photometry, infrared ; H I data Keywords: galaxies: distances and redshifts - galaxies: general - galaxies: ISM - infrared: galaxies - radio lines: galaxies Abstract: A total of 334 Low Surface Brightness galaxies detected in the 2MASS all-sky near-infrared survey have been observed in the 21 cm H I line using the Nancay telescope. All have a Ks-band mean central surface brightness, measured within a 5" radius, fainter than 18mag/arcsec2 and a Ks-band isophotal radius at the 20mag/arcsec2 level larger than 20". We present global H I line parameters for the 171 clearly detected objects and the 23 marginal detections, as well as upper limits for the undetected objects. The 171 clear detections comprise 50 previously uncatalogued objects and 41 objects with a PGC entry only. File Summary:

Note (2): Estimated upper limits to IHI and MHI are 3σ values for 250km/s wide, flat-topped profiles Note (3): Two different line search modes were used: lo in the -500 to 10500km/s range hi in the 9500 to 20500km/s range.
Global notes: Note (G1): Reduced to the RC3 system and corrected for galactic extinction, inclination and redshift effects. Note (G2): LK (resp. LB) is expressed in L_☉,K (resp. L☉,B), and calculated using an absolute solar Ks (resp. B) -band magnitude of 3.33 (resp. 5.48) (Allen, 1973, Astrophysical Quantities).
