An additional 29 galaxies were observed in the Vela ZOA survey region (because of the small numbers they are not discussed any further). The observations were conducted with the Parkes 64m (210 ft) radio telescope, in a single-pixel pointed mode, reaching an rms noise level of typically 2-6mJy over the velocity search range of 400<v<10500km/s. A total of 162 galaxies were detected (plus 14 galaxies in the Vela region). The detection rate is slightly higher than for the Hydra/Antlia region (52% versus 45%) observed in the same way. Description: The Parkes 64m radio telescope1 was used over four observing periods of about 10-14 days each (June 1993, April 1994, July 1995 and September 1996). Here, we report on the observations that cover the Crux and Great Attractor Zone of Avoidance regions. A detailed description of the observational set-up is given in Paper I (Kraan-Korteweg et al. 2002, Cat. J/A+A/391/887). File Summary:

Description of files in "sp" subdirectory: * the spectra (*.mgo files) are ascii files, one per galaxy, with 5 columns: row, flux (mJy), radio velocity (km/s), optical velocity (km/s) and frequency (MHz) * the supmermongo scripts (*.sm files), used to generate the figures for the on-line additional material of the paper (the scripts include the limits on the optical velocities used for the plots, and in a few cases the corrections of an offset in velocities) See also: B/denis : The DENIS database (DENIS Consortium, 2005) VII/233 : The 2MASS Extended sources (IPAC/UMass, 2003-2006) J/A+A/391/887 : Redshifts in the Hydra/Antlia Extension (Kraan-Korteweg+, 2002) Byte-by-byte Description of file: table1.dat tableb2.dat

Note (1): Note as follows: ? = uncertain identification of the HI signal + = more than one signal was found in the pointing or in the associated OFF-observation Note (2): Flag as follows: I = indicates an entry in the IRAS Point Source Catalog (II/125) according to the precepts explained in Woudt & Kraan-Korteweg (2001, Cat. J/A+A/380/441) M = an entry in the 2MASS Extended Objects Catalogue (2MASX, 2003, Cat. VII/233) D = indicates an entry in the DENIS catalogue by Vauglin et al. (2002, Cat. J/A+A/387/1 Note (3): Heliocentric HI radial velocity taken at the midpoint of the HI profile at the 20% level. Note (4): Most spectra have been Hanning-smoothed, except when the line width was smaller than 100km/s or for other reasons (see below), which is indicated with an 'n' for 'no Hanning-smoothing'. Note (5): Notes on individual sources as follows: WKK0969 = see plot of WKK1117 WKK2576 = the signal is blended with WKK2595 and WKK2597 (cf. text), the width and velocity of the narrow peak are given here WKK2597 = see plot of WKK2595 WKK2863 = see plot of WKK2844 WKK4016 = the signal is blended with WKK4022, the velocity measurements refer to the narrow peak at v∼4640km/s only WKK5299 = the parameters are uncertain due to an RFI at the edge of the profile at v∼4500km/s WKK5616 = see plot of WKK5659 WKK5636 = Hanning-smoothed once despite the narrow line, due to ringing in the spectrum WKK5829 = not Hanning-smoothed due to an RFI close to the profile at v=4550km/s WKK5993 = the profile of WKK5999 (see separate pointing) has been excluded from the profile measurement WKK6680 = once Hanning-smoothed for the plot SKK209-5 = the RFI is next to the profile and possibly affects the line width
