J/A+A/435/459       HI data of edge-on spiral galaxies       (Huchtmeier+, 2005)

HI observations of edge-on spiral galaxies. Huchtmeier W.K., Karachentsev I.D., Karachentseva V.E., Kudrya Yu.N., Mitronova S.N. <Astron. Astrophys. 435, 459 (2005)> =2005A&A...435..459H

Fluxes, radial velocities and line widths are given for 121 detected galaxies, as well as search parameters for 147 undetected objects. Most of the detected galaxies are late type (Sbc -- Sdm) spirals with a mean M25/L_B ratio of 2.5 in solar units. (M25 is the total mass within the 25mag/arcsec2 isophote) and a mean hydrogen mass fraction MHI/M25=0.13. Correlations between global parameters are discussed briefly. A comparison with a sample of nearby galaxies (within 10Mpc) demonstrates the validity of the same linear relation between the optical luminosity (LB) and the linear diameter (A25) down to the smallest galaxies. Description: The HI line observations were performed using the Effelsberg 100-m radio telescope during several sessions between October 2001 and April 2002. File Summary:

Note (1): Individual notes: -- RFGC 860, 1308, 2080, 2777, and 3370: for these objects we find multiple objects in the beam (confusion); RFGC 1309 without known radial velocity lies at 1.15' to S from RFGC 1308. The three galaxies RFGC 1308, 1309, 1310 might form a physical triplet; there is mutual contamination within the beam for each of the three targets by the possible group members. -- RFGC 3231: We assume that the observed HI profile is due to Galactic emission. Note (2): Errors of velocity measurements depend on the velocity resolution, the signal-to-noise ratio and the shape of the line profiles. The half power line width is given for all detected galaxies. Line widths at lower levels are only given when the signal-to-noise ratio allows the measurement.
