J/A+AS/141/123). Searching a simultaneous velocity range of either 300 to 5500km/s or 300 to 10500km/s to an rms level of typically 2-4mJy resulted in detections in 61 of the 139 pointings, leading to a total of 66 detections (an additional detection was made in a reference position, and two other pointings revealed two and four independent signals respectively). Except for 2 strong HI emitters identified in the shallow Zone of Avoidance HI survey (Henning et al., 2000AJ....119.2686H), all HI detections are new. File Summary:

Note (1): In three of the pointed observations (RKK1037, RKK1919 and RKK1947) more than one 21-cm detection was identified within the beam and covered velocity range. Some of these HI detections do not have an optical counterpart (INV#). RKK1919B INV1 has no position. Note (2): Code for uncertainty : ":" for uncertainty value "*" for slightly underestimated value

Note (1): Some of the spectra of the non-detections listed in Table 2 do reveal a positive signal. Comparing the recession velocities with independent optical data proves, however, that the observed HI emission in four of the pointings does not originate from the targeted object but from a neighbour at close angular distance. An "*" indicates these HI emissions.
Global notes: Note (G1): Remarks: The B and O are indications that they were detected at the position of that galaxy with the name before it, where B means that it was a second detection in the same HI profile; O it was detected first as a negative signal due to OFF observation (10.5arcmin earlier in RA) of the originally observed object; a means indicates that the Parkes telescope was actually not pointed towards the galaxy listed in Table 1 but towards another galaxy at small angular separation, hence the HI flux could be slightly underestimated (indicated later on with a * in the columns of the HI properties). Note (G2): Code for counterpart in IRAS PSC: I: certain identification P: possible identification Q: questionable See Kraan-Korteweg, 2000, Cat. J/A+AS/141/123 for more details.
