One hundred sixteen of the 2MASX sources and the 16 working database sources were observed using the Nancay radio telescope, usually in the 325 to 11825km/s range, and the other 81 2MASX sources were observed with the Arecibo radio telescope in the -500 to 11000km/s range, and for 9 also in the 9500 to 21000km/s range. Description: The Nancay observations were made in the period June-December 2002, using a total of about 350h of telescope time. A number of follow-up observations were made to check tentative detections in late 2007 and in late 2008. We observed a sample of 81 LSB galaxies in the ZoA from a pre-release version of the 2MASS working database using the refurbished 305-m Arecibo Gregorian radio telescope in November 2000 and January 2001, for a total of about 30h observing time.

Global notes: Note (G1): No. N15: galaxy ESO 371-27 was detected in the beam centred on the undetected target, ESO 371-26. Note (G2): Not corrected for extinction, hence reddened depending on the foreground dust column density by the amount of fJ-K=0.12AB and fH-K=0.05AB
