Abstract:
We present the results of the Northern extension of the HI Parkes Zone
of Avoidance Survey, a blind HI survey utilizing the multibeam
receiver on the Parkes 64m telescope. In the two regions studied here,
l=36°-52° and l=196°-212°, |b|≤5°, we have
detected 77 HI galaxies, 20 of which have been previously detected in
HI. The survey has a median rms noise of 6.0mJy/beam and is complete
to a mean flux density of 22mJy. We have searched for multiwavelength
counterparts to the 77 galaxies detected here: 19, 27, and 11 have a
likely optical, 2MASS (Cat. VII/233), and IRAS (Cat. II/125)
cataloged counterpart, respectively.
Description:
The observations for the Northern extension of the HI Parkes ZOA
survey began in 2000 October and were completed in 2002 May. The data
were taken at the Parkes 64m telescope using the 21cm multibeam
receiver.

Note (1): The flux was calculated over a smaller region to isolate the
galaxy emission from that arising from a nearby galaxy. This may
have led to an underestimation of the total flux.
Note (2): The error we estimate for the integrated flux does not take
into account the uncertainty due to baseline subtraction or the
uncertainty in calibration; the total error on the integrated flux
is likely to be ∼10%-15%.
Note (3): The 20% velocity width could not be accurately measured.
Note (4): The distance to each galaxy, Dist=vLG/H0, was calculated
using its velocity in the Local Group standard of rest,
vLG=vhel+300sin(l)cos(b).

Note (1): Flags, defined as follows:
d = There are two possible counterparts to this source,
2MASS J06254183+0346338 at a separation of 2.3' and
a DSS galaxy at RA=06 25 45.1, DE=03 47 55 (separation = 1.4').
We do not have enough information to decide between the two.
e = We note that there is another possible 2MASS counterpart,
J06303033+0240026, at a separation of 2.7'. This candidate appears
to be of earlier type than that chosen above, but cannot be excluded.
f = Our HI detection was resolved into two galaxies separated by 4' by
the ADBS (Cat. J/ApJS/130/177). We are unable to say to which HI
galaxy the counterpart belongs.
g = In addition to the counterpart listed here, we see another DSS galaxy
at 06:59:38.1+06:25:19 as well as two 2MASS candidates:
J06595034+0623322 (separation = 4.3') and
J06595034+0623322 (separation = 4.4').
From morphology and separation arguments, we believe the candidate
we have chosen is the most likely, but we can not rule out those
listed here.
